Description

Computes the skewness of the values of x.

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

$$N^(-1) sd(x)^(-3) sum_i (x_i - mean(x))^3$$

Usage

skewness(x, na.rm=FALSE)

Arguments

x

a numeric vector containing the values whose skewness is to be computed.

na.rm

a logical value indicating whether NA values should be stripped before the computation proceeds.

Value

• Returns the skewness of x.

Examples

x<-rnorm(100)
skewness(x)
