Compute Skewness of a Vector

This function takes in a vector as it's input and will return the skewness of that vector. The length of this vector must be at least four numbers. The skewness explains the 'tailedness' of the distribution of data.

((1/n) * sum(x - mu})^3) / ((()1/n) * sum(x - mu)^2)^(3/2)

Usage

skewness_vec(.x)

Arguments

.x

A numeric vector of length four or more.

Value
