kurtosis

fun kurtosis(kind: PopulationKind = SAMPLE, excess: Boolean = true): Double(source)

Computes the kurtosis of all observations.

Returns Double.NaN if fewer than 4 observations have been added. Returns -3.0 (excess) or 0.0 (non-excess) if the variance is zero (constant data).

Return

the kurtosis, or Double.NaN if insufficient data.

Parameters

kind

whether to compute sample-adjusted or population kurtosis. Defaults to PopulationKind.SAMPLE.

excess

whether to subtract 3 (the kurtosis of a normal distribution). Defaults to true.
