Cumulative Distribution Function (CDF) Calculator for the F-Distribution
Tweet
This calculator will compute the cumulative distribution function (CDF) for the Fisher F-distribution (i.e., the area under the F-distribution from 0 to x), given the numerator and denominator degrees of freedom, and the upper limit of integration x.
Please supply the necessary parameter values, and then click 'Calculate'.
Degrees of freedom 1:
The first degrees of freedom value. This value is associated with the numerator.
Degrees of freedom 2:
The second degrees of freedom value. This value is associated with the denominator.
x:
The upper limit of integration.
Formulas
The following formulas are involved in the calculation of cumulative distribution function (CDF) values for the F-distribution:
Beta function:
F-distribution cumulative distribution function (CDF):
where
d
1
and
d
2
are the degrees of freedom, and
I
is the regularized lower incomplete beta function.
Lower incomplete beta function:
Regularized lower incomplete beta function:
where the numerator is the lower incomplete beta function, and the denominator is the beta function.
