Subject: Re: Finding the pdf of rv y from that of rv x, where x and y satisfy a
pretty general implicit function
Dear Bugs users,
I would be most grateful for any help with determining the pdf of rv y from
that of rv x using WINBUGS, where x and y satisfy a pretty general implicit
function
F(x,y)=0
For this implict function, one cannot solve x as a function of y
analytically, or vice versa, and one cannot compute dx/dy analytically.
For example, how can one determine the pdf of rv y from that of rv x using
WINBUGS, where x and y satisfy
F(x,y)=a+b*x+c*x^2+d*x^3+e*x^4+f*x^5-y=0
where a, b, c, d, e and f are real constants, and x and y are real.
Any help would be much appreciated
Best wishes
