The Rayleigh Distribution¶
-
gsl_ran_rayleigh(sigma)¶
This function returns a random variate from the Rayleigh distribution with scale parameter
sigma. The distribution is,\[p(x) dx = {x \over \sigma^2} \exp(- x^2/(2 \sigma^2)) dx\]for \(x > 0\).
-
gsl_ran_rayleigh_pdf(x, sigma)¶
This function computes the probability density \(p(x)\) at \(x\) for a Rayleigh distribution with scale parameter
sigma, using the formula given above.
-
gsl_ran_rayleigh_P(x, sigma)¶
-
gsl_ran_rayleigh_Q(x, sigma)¶
-
gsl_ran_rayleigh_Pinv(P, sigma)¶
-
gsl_ran_rayleigh_Qinv(Q, sigma)¶
These functions compute the cumulative distribution functions \(P(x), Q(x)\) and their inverses for the Rayleigh distribution with scale parameter
sigma.
