# skewness: Skewness In analyzer: Data Analysis and Automated R Notebook Generation

## Description

skewness calculates the skewness

## Usage

 1 skewness(x, na.rm = T) 

## Arguments

 x a numeric vector, matrix or a data.frame na.rm (logical) Should missing values be removed?

## Details

This function calculates the skewness of data which is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The formula used is:

\frac{E[(X-μ)^{3}]}{(E[(X-μ)^2])^\frac{3}{2}}

. This formula is the typical definition used in many older textbooks and wikipedia

## Value

returns a single value if x is a vector, otherwise a named vector of size = ncol(x).

## Examples

 1 2 3 4 5 # for a single vector skewness(mtcars\$mpg) # for a dataframe skewness(mtcars)
