-\rhead{Ordnungsstatistik und Beta-Funktion}
-In diesem Abschnitt ist $X$ eine Zufallsvariable mit der Verteilungsfunktion
-$F_X(x)$, und $X_i$, $1\le i\le n$ sei ein Stichprobe von unabhängigen
-Zufallsvariablen, die wie $X$ verteilt sind.
-Ziel ist, die Verteilungsfunktion und die Wahrscheinlichkeitsdichte
-des grössten, zweitgrössten, $k$-t-grössten Wertes in der Stichprobe
-zu finden.
-Wir schreiben $[n]=\{1,\dots,n\}$ für die Menge der natürlichen
-Zahlen von zwischen $1$ und $n$.

-\subsection{Verteilung von $\operatorname{max}(X_1,\dots,X_n)$ und
-$\operatorname{min}(X_1,\dots,X_n)$
-\label{dreieck:subsection:minmax}}
-Die Verteilungsfunktion von $\operatorname{max}(X_1,\dots,X_n)$ hat
-den Wert
-\begin{align*}
-F_{\operatorname{max}(X_1,\dots,X_n)}(x)
-&=
-P(\operatorname{max}(X_1,\dots,X_n) \le x)
-\\
-&=
-P(X_1\le x\wedge \dots \wedge X_n\le x)
-\\
-&=
-P(X_1\le x) \cdot \ldots \cdot P(X_n\le x)
-\\
-&=
-P(X\le x)^n
-=
-F_X(x)^n.
-\end{align*}
-Für die Gleichverteilung ist
-\[
-F_{\text{equi}}(x)
-=
-\begin{cases}
-0&\qquad x< 0
-\\
-x&\qquad 0\le x\le 1
-\\
-1&\qquad 1<x.
-\end{cases}
-\]
-In diesem Fall ist Verteilung des Maximums
-\[
-F_{\operatorname{max}(X_1,\dots,X_n)}(x)
-=
-\begin{cases}
-0&\qquad x<0\\
-x^n&\qquad 0\le x\le 1\\
-1&\qquad 1 < x.

-Mit der zugehörigen Wahrscheinlichkeitsdichte

-\frac{d}{dx}
-F_{\operatorname{max}(X_1,\dots,X_n)}(x)
-=
-\begin{cases}
-nx^{n-1}&\qquad 0\le x\le 1\\

-=

-\]
-berechnen.
-
-Ganz analog kann man auch die Verteilungsfunktion von
-$\operatorname{min}(X_1,\dots,X_n)$ bestimmen.
-Sie ist
-\begin{align*}
-F_{\operatorname{min}(X_1,\dots,X_n)}(x)
-&=
-P(x\le X_1\vee \dots \vee x\le X_n)
-\\
-&=
-1-
-P(x > X_1\wedge \dots \wedge x > X_n)
-\\
-&=
-1-
-(1-P(x\le X_1)) \cdot\ldots\cdot (1-P(x\le X_n))
-\\
-&=
-1-(1-F_X(x))^n,
-\end{align*}
-Im Speziellen für im Intervall $[0,1]$ gleichverteilte $X_i$ ist die
-Verteilungsfunktion des Minimums
-\[
-F_{\operatorname{min}(X_1,\dots,X_n)}(x)
-=
-\begin{cases}
-0        &\qquad x<0        \\
-1-(1-x)^n&\qquad 0\le x\le 1\\
-1        &\qquad 1 < x
-\end{cases}
-\]
-mit Wahrscheinlichkeitsdichte
-\[
-\varphi_{\operatorname{min}(X_1,\dots,X_n)}
-=
-\frac{d}{dx}
-F_{\operatorname{min}(X_1,\dots,X_n)}
-=
-\begin{cases}
-n(1-x)^{n-1}&\qquad 0\le x\le 1\\
-0           &\qquad \text{sonst}
-\end{cases}
-\]
-und Erwartungswert
-\begin{align*}
-E(\operatorname{min}(X_1,\dots,X_n)
-&=
-\int_{-\infty}^\infty x\varphi_{\operatorname{min}(X_1,\dots,X_n)}(x)\,dx
-=
-\int_0^1 x\cdot n(1-x)^{n-1}\,dx
-\\
-&=
-\bigl[ -x(1-x)^n \bigr]_0^1 + \int_0^1 (1-x)^n\,dx
-=
-\biggl[
--
-\frac{1}{n+1}
-(1-x)^{n+1}
-\biggr]_0^1
-=
-\frac{1}{n+1}.
-\end{align*}
-Es ergibt sich daraus als natürlich Verallgemeinerung die Frage nach
-der Verteilung des zweitegrössten oder zweitkleinsten Wertes unter den
-Werten $X_i$.
-
-\subsection{Der $k$-t-grösste Wert}
-Sie wieder $X_i$ eine Stichprobe von $n$ unabhängigen wie $X$ verteilten
-Zufallsvariablen.
-Diese werden jetzt der Grösse nach sortiert, die sortierten Werte werden
-mit
-\[
-X_{1:n} \le X_{2:n} \le \dots \le X_{(n-1):n} \le X_{n:n}
-\]
-bezeichnet.
-Die Grössen $X_{k:n}$ sind Zufallsvariablen, sie heissen die $k$-ten
-Ordnungsstatistiken.
-Die in Abschnitt~\ref{dreieck:subsection:minmax} behandelten Zufallsvariablen
-$\operatorname{min}(X_1,\dots,X_n)$
-und
-$\operatorname{max}(X_1,\dots,X_n)$
-sind die Fälle
-\begin{align*}
-X_{1:n} &= \operatorname{min}(X_1,\dots,X_n) \\
-X_{n:n} &= \operatorname{max}(X_1,\dots,X_n).
-\end{align*}
-
-Um den Wert der Verteilungsfunktion von $X_{k:n}$ zu berechnen, müssen wir 
-die Wahrscheinlichkeit bestimmen, dass $k$ der $n$ Werte $X_i$ $x$ nicht
-übersteigen.
-Der $k$-te Wert $X_{k:n}$ übersteigt genau dann $x$ nicht, wenn
-mindestens $k$ der Zufallswerte $X_i$ $x$ nicht übersteigen, also
-\[
-P(X_{k:n} \le x)
-=
-P\left(
-|\{i\in[n]\,|\, X_i\le x\}| \ge k
-\right).
-\]
-
-Das Ereignis $\{X_i\le x\}$ ist eine Bernoulli-Experiment, welches mit
-Wahrscheinlichkeit $F_X(x)$ eintritt.
-Die Anzahl der Zufallsvariablen $X_i$, die $x$ übertreffen, ist also
-Binomialverteilt mit $p=F_X(x)$.
-Damit haben wir gefunden, dass mit Wahrscheinlichkeit
-\begin{equation}
-F_{X_{k:n}}(x)
-=
-P(X_{k:n}\le x)
-=
-\sum_{i=k}^n \binom{n}{i}F_X(x)^i (1-F_X(x))^{n-i}
-\label{dreieck:eqn:FXkn}
-\end{equation}
-mindestens $k$ der Zufallsvariablen den Wert $x$ überschreiten.
-
-\subsubsection{Wahrscheinlichkeitsdichte der Ordnungsstatistik}
-Die Wahrscheinlichkeitsdichte der Ordnungsstatistik kann durch Ableitung
-von \eqref{dreieck:eqn:FXkn} gefunden, werden, sie ist
-\begin{align*}
-\varphi_{X_{k:n}}(x)
-&=
-\frac{d}{dx}
-F_{X_{k:n}}(x)
-\\
-&=
-\sum_{i=k}^n
-\binom{n}{i}
-\bigl(
-iF_X(x)^{i-1}\varphi_X(x) (1-F_X(x))^{n-i}
--
-F_X(x)^k
-(n-i)
-(1-F_X(x))^{n-i-1}
-\varphi_X(x)
-\bigr)
-\\
-&=
-\sum_{i=k}^n
-\binom{n}{i}
-\varphi_X(x)
-F_X(x)^{i-1}(1-F_X(x))^{n-i-1}
-\bigl(
-iF_X(x)-(n-i)(1-F_X(x))
-\bigr)
-\\
-&=
-\varphi_X(x)
-\biggl(
-\sum_{i=k}^n i\binom{n}{i} F_X(x)^{i-1}(1-F_X(x))^{n-i}
--
-\sum_{j=k}^n (n-j)\binom{n}{j} F_X(x)^{j}(1-F_X(x))^{n-j-1}
-\biggr)
-\\
-&=
-\varphi_X(x)
-\biggl(
-\sum_{i=k}^n i\binom{n}{i} F_X(x)^{i-1}(1-F_X(x))^{n-i}
--
-\sum_{i=k+1}^{n+1} (n-i+1)\binom{n}{i-1} F_X(x)^{i-1}(1-F_X(x))^{n-i}
-\biggr)
-\\
-&=
-\varphi_X(x)
-\biggl(
-k\binom{n}{k}F_X(x)^{k-1}(1-F_X(x))^{n-k}
-+
-\sum_{i=k+1}^{n+1}
-\left(
-i\binom{n}{i} 
--
-(n-i+1)\binom{n}{i-1}
-\right)
-F_X(x)^{i-1}(1-F_X(x))^{n-i}
-\biggr)
-\end{align*}
-Mit den wohlbekannten Identitäten für die Binomialkoeffizienten
-\begin{align*}
-i\binom{n}{i} 
--
-(n-i+1)\binom{n}{i-1}
-&=
-n\binom{n-1}{i-1}
--
-n
-\binom{n-1}{i-1}
-=
-0
-\end{align*}
-folgt jetzt
-\begin{align*}
-\varphi_{X_{k:n}}(x)
-&=
-\varphi_X(x)k\binom{n}{k} F_X(x)^{k-1}(1-F_X(x))^{n-k}(x).
-\intertext{Im Speziellen für gleichverteilte Zufallsvariablen $X_i$ ist
-}
-\varphi_{X_{k:n}}(x)
-&=
-k\binom{n}{k} x^{k-1}(1-x)^{n-k}.
-\end{align*}
-Dies ist die Wahrscheinlichkeitsdichte einer Betaverteilung
-\[
-\beta(k,n-k+1)(x)
-=
-\frac{1}{B(k,n-k+1)}
-x^{k-1}(1-x)^{n-k}.
-\]
-Tatsächlich ist die Normierungskonstante 
-\begin{align}
-\frac{1}{B(k,n-k+1)}
-&=
-\frac{\Gamma(n+1)}{\Gamma(k)\Gamma(n-k+1)}
-=
-\frac{n!}{(k-1)!(n-k)!}.
-\label{dreieck:betaverteilung:normierung1}
-\end{align}
-Andererseits ist
-\[
-k\binom{n}{k}
-=
-k\frac{n!}{k!(n-k)!}
-=
-\frac{n!}{(k-1)!(n-k)!},
-\]
-in Übereinstimmung mit~\eqref{dreieck:betaverteilung:normierung1}.
-Die Verteilungsfunktion und die Wahrscheinlichkeitsdichte der
-Ordnungsstatistik sind in Abbildung~\ref{dreieck:fig:order} dargestellt.
-
-\begin{figure}
-\centering
-\includegraphics{papers/dreieck/images/order.pdf}
-\caption{Verteilungsfunktion und Wahrscheinlichkeitsdichte der
-Ordnungsstatistiken $X_{k:n}$ einer gleichverteilung Zuvallsvariable
-mit $n=10$.
-\label{dreieck:fig:order}}
-\end{figure}
-
-\subsubsection{Erwartungswert}
-Mit der Wahrscheinlichkeitsdichte kann man jetzt auch den Erwartungswerte
-der $k$-ten Ordnungsstatistik bestimmen.
-Die Rechnung ergibt:
-\begin{align*}
-E(X_{k:n})
-&=
-\int_0^1 x\cdot k\binom{n}{k} x^{k-1}(1-x)^{n-k}\,dx
-=
-k
-\binom{n}{k}
-\int_0^1
-x^{k}(1-x)^{n-k}\,dx.
-\intertext{Dies ist das Beta-Integral}
-&=
-k\binom{n}{k}
-B(k+1,n-k+1)
-\intertext{welches man durch Gamma-Funktionen bzw.~durch Fakultäten wie in}
-&=
-k\frac{n!}{k!(n-k)!}
-\frac{\Gamma(k+1)\Gamma(n-k+1)}{n+2}
-=
-k\frac{n!}{k!(n-k)!}
-\frac{k!(n-k)!}{(n+1)!}
-=
-\frac{k}{n+1}
-\end{align*}
-ausdrücken kann.
-Die Erwartungswerte haben also regelmässige Abstände, sie sind in
-Abbildung~\ref{dreieck:fig:order} als blaue vertikale Linien eingezeichnet.
-
-\subsubsection{Varianz}
-Auch die Varianz lässt sich einfach berechnen, dazu muss zunächst
-der Erwartungswert von $X_{k:n}^2$ bestimmt werden.
-Er ist
-\begin{align*}
-E(X_{k:n}^2)
-&=
-\int_0^1 x^2\cdot k\binom{n}{k} x^{k-1}(1-x)^{n-k}\,dx
-=
-k
-\binom{n}{k}
-\int_0^1
-x^{k+1}(1-x)^{n-k}\,dx.
-\intertext{Auch dies ist ein Beta-Integral, nämlich}
-&=
-k\binom{n}{k}
-B(k+2,n-k+1)
-=
-k\frac{n!}{k!(n-k)!}
-\frac{(k+1)!(n-k)!}{(n+2)!}
-=
-\frac{k(k+1)}{(n+1)(n+2)}.
-\end{align*}
-Die Varianz wird damit
-\begin{align}
-\operatorname{var}(X_{k:n})
-&=
-E(X_{k:n}^2) - E(X_{k:n})^2
-\notag
-\\
-&
-=
-\frac{k(k+1)}{(n+1)(n+2)}-\frac{k^2}{(n+1)^2}
-=
-\frac{k(k+1)(n+1)-k^2(n+2)}{(n+1)^2(n+2)}
-=
-\frac{k(n-k+1)}{(n+1)^2(n+2)}.
-\label{dreieck:eqn:ordnungsstatistik:varianz}
-\end{align}
-In Abbildung~\ref{dreieck:fig:order} ist die Varianz der
-Ordnungsstatistik $X_{k:n}$ für $k=7$ und $n=10$ als oranges
-Rechteck dargestellt.
-
-\begin{figure}
-\centering
-\includegraphics[width=0.84\textwidth]{papers/dreieck/images/beta.pdf}
-\caption{Wahrscheinlichkeitsdichte der Beta-Verteilung
-$\beta(a,b,x)$
-für verschiedene Werte der Parameter $a$ und $b$.
-Die Werte des Parameters für einen Graphen einer Beta-Verteilung
-sind als Punkt im kleinen Quadrat rechts
-im Graphen als Punkt mit der gleichen Farbe dargestellt.
-\label{dreieck:fig:betaverteilungn}}
-\end{figure}
-
-Die Formel~\eqref{dreieck:eqn:ordnungsstatistik:varianz}
-besagt auch, dass die Varianz der proportional ist zu $k((n+1)-k)$.
-Dieser Ausdruck ist am grössten für $k=(n+1)/2$, die Varianz ist
-also grösser für die ``mittleren'' Ordnungstatistiken als für die
-extremen $X_{1:n}=\operatorname{min}(X_1,\dots,X_n)$ und
-$X_{n:n}=\operatorname{max}(X_1,\dots,X_n)$.

-Ein paar Hinweise für die korrekte Formatierung des Textes
-\begin{itemize}
-\item
-Absätze werden gebildet, indem man eine Leerzeile einfügt.
-Die Verwendung von \verb+\\+ ist nur in Tabellen und Arrays gestattet.
-\item
-Die explizite Platzierung von Bildern ist nicht erlaubt, entsprechende
-Optionen werden gelöscht. 
-Verwenden Sie Labels und Verweise, um auf Bilder hinzuweisen.
-\item
-Beginnen Sie jeden Satz auf einer neuen Zeile. 
-Damit ermöglichen Sie dem Versionsverwaltungssysteme, Änderungen
-in verschiedenen Sätzen von verschiedenen Autoren ohne Konflikt 
-anzuwenden.
-\item 
-Bilden Sie auch für Formeln kurze Zeilen, einerseits der besseren
-Übersicht wegen, aber auch um GIT die Arbeit zu erleichtern.

+Nämlich ist eine Verfolgungskurve die Kurve, die ein Verfolger abfährt während er sein Ziel verfolgt.

+
+Je nach Verfolgungsstrategie die der Verfolger verwendet, entsteht eine andere DGL.
+Für dieses konkrete Beispiel wird einfachheitshalber die simpelste Strategie gewählt.
+Bei dieser Strategie bewegt sich der Verfolger immer direkt auf sein Ziel hinzu.
+Womit der Geschwindigkeitsvektor des Verfolgers zu jeder Zeit direkt auf das Ziel zeigt.
+
+Um die DGL dieses Problems herzuleiten wird der Sachverhalt in der Grafik \eqref{pursuer:grafik1} aufgezeigt.
+Der Punkt $P$ ist der Verfolger und der Punkt $A$ ist sein Ziel.
+
+Um dies mathematisch beschreiben zu können, wird der Richtungsvektor
+\begin{equation}
+    \frac{A-P}{|A-P|}
+    =
+    \frac{\dot{P}}{|\dot{P}|}
+\end{equation}
+benötigt. Durch die Subtraktion der Ortsvektoren $\overrightarrow{OP}$ und $\overrightarrow{OA}$ entsteht ein Vektor der vom Punkt $P$ auf $A$ zeigt.
+Da die Länge dieses Vektors beliebig sein kann, wird durch Division mit dem Betrag, die Länge auf eins festgelegt.
+Aus dem Verfolgungsproblem ist auch ersichtlich, dass die Punkte $A$ und $P$ nicht am gleichen Ort starten und so eine Division durch Null ausgeschlossen ist.
+Wenn die Punkte $A$ und $P$ trotzdem am gleichen Ort starten, ist die Lösung trivial.
+
+Nun wird die Gleichung mit deren rechten Seite skalar multipliziert, um das Gleichungssystem von zwei auf eine Gleichung zu reduzieren.
+\begin{equation}
+    \label{pursuer:pursuerDGL}
+    \frac{A-P}{|A-P|}\cdot \frac{\dot{P}}{|\dot{P}|}
+    =
+    1
+\end{equation}
+Diese DGL ist der Kern des Verfolgungsproblems, insofern sich der Verfolger immer direkt auf sein Ziel zubewegt.
+
+
+\subsection{Beispiel}
+Das Verfolgungsproblem wird mithilfe eines konkreten Beispiels veranschaulicht. Dafür wird die einfachste Strategie verwendet, bei der sich der Verfolger direkt auf sein Ziel hinzu bewegt. Für dieses Problem wurde bereits die DGL \eqref{pursuer:pursuerDGL} hergeleitet.
+
+Um dieses Beispiel einfach zu halten, wird für den Verfolger und das Ziel jeweils eine konstante Geschwindigkeit von eins gewählt. Das Ziel wiederum startet im Ursprung und bewegt sich linear auf der positiven Y-Achse.
+
+\begin{align}
+    v_P^2
+    &=
+    \dot{P}\cdot\dot{P}
+    =
+    1
+    \\[5pt]
+    v_A
+    &=
+    1
+    \\[5pt]
+    A
+    &=
+    \begin{pmatrix}
+    	0 \\
+    	v_A\cdot t
+    \end{pmatrix}
+	=
+	\begin{pmatrix}
+		0 \\
+		t
+	\end{pmatrix}
+	\\[5pt]
+	P
+	&=
+	\begin{pmatrix}
+		x \\
+		y
+	\end{pmatrix}
+\end{align}
+
+Die Anfangsbedingungen dieses Problems sind.
+
+\begin{align}
+	y(t)\bigg|_{t=0}
+	&=
+	y_0
+	\\[5pt]
+	x(t)\bigg|_{t=0}
+	&=
+	x_0 \\[5pt]
+	\frac{\,dy}{\,dx}(t)\bigg|_{t=0}
+	&=
+	\frac{y_A(t) -y_P(t)}{x_A(t)-x_P(t)}\bigg|_{t=0}
+\end{align}
+
+Mit den vorangegangenen Definitionen kann nun die DGL \eqref{pursuer:pursuerDGL} gelöst werden.
+Dafür wird als erstes das Skalarprodukt ausgerechnet.
+
+\begin{equation}
+	\dfrac{-x\cdot\dot{x}+(t-y)\cdot\dot{y}}{\sqrt{x^2+(t-y)^2}} = 1
+\end{equation}
+
+
+
+

-
-Ein paar Hinweise für die korrekte Formatierung des Textes
-\begin{itemize}
-\item
-Absätze werden gebildet, indem man eine Leerzeile einfügt.
-Die Verwendung von \verb+\\+ ist nur in Tabellen und Arrays gestattet.
-\item
-Die explizite Platzierung von Bildern ist nicht erlaubt, entsprechende
-Optionen werden gelöscht. 
-Verwenden Sie Labels und Verweise, um auf Bilder hinzuweisen.
-\item
-Beginnen Sie jeden Satz auf einer neuen Zeile. 
-Damit ermöglichen Sie dem Versionsverwaltungssysteme, Änderungen
-in verschiedenen Sätzen von verschiedenen Autoren ohne Konflikt 
-anzuwenden.
-\item 
-Bilden Sie auch für Formeln kurze Zeilen, einerseits der besseren
-Übersicht wegen, aber auch um GIT die Arbeit zu erleichtern.
-\end{itemize}
