The Logistic Distribution

Random: double gsl_ran_logistic (const gsl_rng * r, double a)

This function returns a random variate from the logistic distribution. The distribution function is,

for @math{-\infty < x < +\infty}.

Function: double gsl_ran_logistic_pdf (double x, double a)

This function computes the probability density @math{p(x)} at x for a logistic distribution with scale parameter a, using the formula given above.
