FRatio

public enum FRatio

F Ratio distribution

  • Returns a SSProbDistParams struct containing mean, variance, kurtosis and skewness of the F ratio distribution.

    Throws

    SSSwiftyStatsError if df1 <= 0 and/or df2 <= 0

    Declaration

    Swift

    public static func para<FPT>(numeratorDF df1: FPT, denominatorDF df2: FPT) throws -> SSProbDistParams<FPT> where FPT : Decodable, FPT : Encodable, FPT : SSFloatingPoint

    Parameters

    df1

    numerator degrees of freedom
    df2

    denominator degrees of freedom

  • Returns the pdf of the F-ratio distribution.

    Throws
