19.16 The Lognormal Distribution
- Function: double gsl_ran_lognormal (const gsl_rng * r, double zeta, double sigma)
This function returns a random variate from the lognormal distribution. The distribution function is, for x > 0.
- Function: double gsl_ran_lognormal_pdf (double x, double zeta, double sigma)
This function computes the probability density p(x) at x for a lognormal distribution with parameters zeta and sigma, using the formula given above.
- Function: double gsl_cdf_lognormal_P (double x, double zeta, double sigma)
- Function: double gsl_cdf_lognormal_Q (double x, double zeta, double sigma)
- Function: double gsl_cdf_lognormal_Pinv (double P, double zeta, double sigma)
- Function: double gsl_cdf_lognormal_Qinv (double Q, double zeta, double sigma)
These functions compute the cumulative distribution functions P(x), Q(x) and their inverses for the lognormal distribution with parameters zeta and sigma.
