Module rgsl::randist::f_distribution
[−]
[src]
The F-distribution arises in statistics. If Y_1 and Y_2 are chi-squared deviates with \nu_1 and \nu_2 degrees of freedom then the ratio,
X = { (Y_1 / \nu_1) \over (Y_2 / \nu_2) }
has an F-distribution F(x;\nu_1,\nu_2).
Functions
fdist |
This function returns a random variate from the F-distribution with degrees of freedom nu1 and nu2. The distribution function is, |
fdist_P |
This function computes the cumulative distribution functions P(x), Q(x) and their inverses for the F-distribution with nu1 and nu2 degrees of freedom. |
fdist_Pinv |
This function computes the cumulative distribution functions P(x), Q(x) and their inverses for the F-distribution with nu1 and nu2 degrees of freedom. |
fdist_Q |
This function computes the cumulative distribution functions P(x), Q(x) and their inverses for the F-distribution with nu1 and nu2 degrees of freedom. |
fdist_Qinv |
This function computes the cumulative distribution functions P(x), Q(x) and their inverses for the F-distribution with nu1 and nu2 degrees of freedom. |
fdist_pdf |
