The Rayleigh Tail Distribution

Random: double gsl_ran_rayleigh_tail (const gsl_rng * r, double a double sigma)

This function returns a random variate from the tail of the Rayleigh distribution with scale parameter sigma and a lower limit of a. The distribution is,

for @math{x > a}.

Function: double gsl_ran_rayleigh_tail_pdf (double x, double a, double sigma)

This function computes the probability density @math{p(x)} at x for a Rayleigh tail distribution with scale parameter sigma and lower limit a, using the formula given above.
