Problem: Verteilung von $P^G$ gesucht bei gegebenen $P^X$:
|
||||
\begin{enumerate}
|
||||
\item Funktionaldeterminante ($J_{G(x)}$) von $G$ berechnen
|
||||
\item Umkehrabbildung $G^*$ berechnen. Alle Zufallsvariablen werden
|
||||
werden mittels Funktionen verändert: z.B: $y_1 = x_1/x_2$.
|
||||
Jede i-te Funktion nach $x_i$ auflösen.
|
||||
\item Gesuchte Funktion: $g(y) = f(G^*(y))\frac{1}{|J_G(G^*(y))|}$\\
|
||||
$\longrightarrow$ Setze für alle $x_i$ dementsprechend $y_i$ ein und multipliziere
|
||||
mit Kehrwehrt von Funktionaldeterminante.
