{{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`.
