Hi, I was wondering if it’s possible to use Stan to simply sample from a density that I know the formula of up to proportionality?
Usually if I just want to sample from a density, then I might just write something like:
parameters {
y;
}
model {
y ~ some_pdf
}
But if I want to sample from a density proportional to e^(-x^4/8), how do I do this now?
Thanks in advance,
Ryan
