kurtosis {e1071}R Documentation

Kurtosis

Description

Computes the kurtosis of the values of x.

If N = length(x), then the kurtosis of x is defined as

N^(-1) var(x)^(-2) sum_i (x_i - mean(x))^4 - 3

Usage

kurtosis(x, na.rm=FALSE)

Arguments

x a numeric vector containing the values whose kurtosis is to be computed.
na.rm a logical value indicating whether NA values should be stripped before the computation proceeds.

Value

Returns the kurtosis of x.

Examples

x<-rnorm(100)
kurtosis(x)
