RiskF

Description

RiskF(v1,v2) specifies an F distribution has two degrees of freedom, v1 and v2. The F distribution is used primarily in statistical hypothesis testing to test the equality of two population variances.

Examples

RiskF(1,2) returns an F distribution with degrees of freedom parameters 1 and 2.

RiskF(C12,C13) returns an F distribution with degrees of freedom paramenters taken from cells C12 and C13.

Guidelines

v1 and v2 must be positive integers.

Parameters
