#include <IMP/isd/FNormal.h>
Probability density function and -log(p) of normal sampling from some function F. If A is drawn from the F-Normal distribution then F(A) is drawn from a normal distribution with mean F(M) and standard deviation sigma (w/r F(A)).
Arguments: F(A), J(A) the derivative of F w/r to A, F(M), and sigma. The distribution is normalized with respect to the variable A. Note that the mean and standard deviation with respect to A may not be M and sigma.
Example: If F is the log function, the F-normal distribution is the lognormal distribution with mean log(M) and standard deviation sigma (wrt. log(A)).
