Calculate Univariate Kurtosis for a Vector or Matrix

Description

Calculate univariate kurtosis for a vector or matrix (algorithm G2 in Joanes & Gill, 1998). Note that, as defined in this function, the expected kurtosis of a normally distributed variable is 0 (i.e., not 3).

Usage

kurt(x)

Arguments

x

Either a vector or matrix of numeric values.

Value

Kurtosis for each column in x.
