### 20.37 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, 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.
