Probability Density Function (PDF) Calculator for the F-Distribution
Tweet
This calculator will compute the probability density function (PDF) for the Fisher F-distribution, given the numerator and denominator degrees of freedom, and the point at which to evaluate the function 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 point at which to evaluate the function.
Formulas
The following formulas are involved in the calculation of probability density function (PDF) values for the F-distribution:
Beta function:
F-distribution probability density function (PDF):
where
d
1
and
d
2
are the degrees of freedom, and
B
is the beta function.
