F Probability Calculator

F Probability calculator; computes the integral and inverse integral for the F(df1, df2) distribution. Plots of the probability density function and cumulative distribution function can also be requested.

F Distribution

Element Name Description
Inverse Creates the inverse of the integral; specify a desired p-value (e.g., significance level) to compute the critical variate value for the respective distribution.
1 - Cumulative p Set this option to True to compute the (critical) variate value for the specified distribution based on a 1-cumulative-p value, or the 1-cumulative-p value based on a specified (critical) variate value.
Plots density function Plots the probability density function.
Plots distribution function Plots the distribution function.
Variate value F Specifies the (critical) variate value for the computations.
p-value Specifies the p-value for computations.
Parameter df 1 Specifies the value for the first parameter: Degrees of freedom df 1.
Parameter df 2 Specifies the value for the second parameter: Degrees of freedom df 2.
