Bowley's Univariate Skewness

Description

Compute Bowley's Univariate Skewness.

Usage

BowleySkew(x)

Arguments

x

a vector of original observations.

Details

Bowley's skewness is defined in terms of quantiles as

\hat{\gamma} = \frac{Q_3 + Q_1 - 2 Q_2}{Q_3 - Q_1}

where Q_i is the ith quartile i=1,2,3 of the data.

Value

BowleySkew gives the Bowley's univariate skewness of the data.

Examples

# Compute Bowley's univariate skewness

set.seed(2019)
x <- rnorm(1000) # Normal Distribution
BowleySkew(x)

set.seed(2019)
y <- rlnorm(1000, meanlog = 1, sdlog = 0.25) # Log-normal Distribution
BowleySkew(y)
