Dear R users,
Given a user-defined cumulative distribution function F, I want to
compute F^{-1}(x).
Isn't this quantile()? (But pay attention to the type .... some say
to use type=1.)
Alternatively: If q = CDF(x) then generate a matrix of independently
random (q,x) pairs on a large sample. Wouldn't the matrix of (x,q)
pairs then be something to work with?
(This has been asked several many times on R-help, so you could
practice your use of the search facilities. Here's a MarkMail link:
