{{alias}}( [d1, d2] )
Returns an F distribution object.
Parameters
----------
d1: number (optional)
Numerator degrees of freedom. Must be greater than `0`. Default: `1.0`.
d2: number (optional)
Denominator degrees of freedom. Must be greater than `0`.
Default: `1.0`.
Returns
-------
f: Object
Distribution instance.
f.d1: number
Numerator degrees of freedom. If set, the value must be greater than
`0`.
f.d2: number
Denominator degrees of freedom. If set, the value must be greater than
`0`.
f.entropy: number
Read-only property which returns the differential entropy.
f.kurtosis: number
Read-only property which returns the excess kurtosis.
f.mean: number
Read-only property which returns the expected value.
f.mode: number
Read-only property which returns the mode.
f.skewness: number
Read-only property which returns the skewness.
f.stdev: number
Read-only property which returns the standard deviation.
f.variance: number
Read-only property which returns the variance.
f.cdf: Function
Evaluates the cumulative distribution function (CDF).
f.pdf: Function
Evaluates the probability density function (PDF).
f.quantile: Function
Evaluates the quantile function at probability `p`.
