kurtosis: 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)
