FRatioDistribution
FRatioDistribution[n, m]
represents an F-ratio distribution with n numerator and m denominator degrees of freedom.
Details
- FRatioDistribution is also known as the Fisher-Snedecor distribution.
- The probability density for value
in an F-ratio distribution is proportional to 
for 
, and is zero for 
. » - For integer n and m, the F-ratio distribution gives the distribution of the ratio of variances for samples from normal distributions.
- FRatioDistribution allows n and m to be any positive real numbers.
- FRatioDistribution can be used with such functions as Mean, CDF, and RandomVariate. »
