# fstat

## PURPOSE

% Compute mean and variance of the F distribution.

## SYNOPSIS

function [mn, v] = fstat (m, n)

## DESCRIPTION

```% -*- texinfo -*-
% @deftypefn {Function File} {[@var{mn}, @var{v}] =} fstat (@var{m}, @var{n})
% Compute mean and variance of the F distribution.
%
%
% @itemize @bullet
% @item
% @var{m} is the first parameter of the F distribution. The elements
% of @var{m} must be positive
%
% @item
% @var{n} is the second parameter of the F distribution. The
% elements of @var{n} must be positive
% @end itemize
% @var{m} and @var{n} must be of common size or one of them must be scalar
%
%
% @itemize @bullet
% @item
% @var{mn} is the mean of the F distribution. The mean is undefined for
% @var{n} not greater than 2
%
% @item
% @var{v} is the variance of the F distribution. The variance is undefined
% for @var{n} not greater than 4
% @end itemize

% @example
% @group

% @group
% [mn, v] = fstat (m, 5)
