The t-distribution arises in statistics. If @math{Y_1} has a normal
distribution and @math{Y_2} has a chi-squared distribution with
@math{\nu} degrees of freedom then the ratio,
has a t-distribution @math{t(x;\nu)} with @math{\nu} degrees of freedom.
- Random: double gsl_ran_tdist (const gsl_rng * r, double nu)
-
This function returns a random variate from the t-distribution. The
distribution function is,
for @math{-\infty < x < +\infty}.
- Function: double gsl_ran_tdist_pdf (double x, double nu)
-
This function computes the probability density @math{p(x)} at x
for a t-distribution with nu degrees of freedom, using the formula
given above.
