I need to generate good quality of random numbers from univariate
normal distribution for further transformation. I tried rnorm in R but
it was not good sometimes. Someone said C++ standard library or
Fortran's built-in functions for that are good. I found that there is
double norm_rand() in R-extension. Does this function, norm_rand()
use the same algorithm as rnorm in R or something similar in C/C++? Or
does anyone know which one between norm_rand() in R-extension and
rnorm in R is better? If anyone could help, I would appreciate it.
