24. def willsonLower(sqlContext: SQLContext, confidence: Double = 0.95, minBound: Double = 0.0): UserDefinedFunction

    Utility used to create UDF-s for Willson confidence interval estimation.

    Utility used to create UDF-s for Willson confidence interval estimation. Mainly copied from org.apache.commons.math3.stat.interval.WilsonScoreInterval, but optimized for multiple evaluations.

    See https://habrahabr.ru/company/darudar/blog/143188/ for details.

    confidence

    Confidence level (95% by default)

    minBound

    Minimum lower bound value (bellow that result is reset to 0 to achive higher sparsity).

    returns

    Function for estimation of Wilson confidence interval lower bound.
