19.37 The Logarithmic Distribution

Function: unsigned int gsl_ran_logarithmic (const gsl_rng * r, double p)
This function returns a random integer from the logarithmic distribution. The probability distribution for logarithmic random variates is,
p(k) = {-1 \over \log(1-p)} {(p^k \over k)}

for k >= 1.

Function: double gsl_ran_logarithmic_pdf (unsigned int k, double p)
This function computes the probability p(k) of obtaining k from a logarithmic distribution with probability parameter p, using the formula given above.
