Check distribution symmetry
Description
Uses Hotelling and Solomons test of symmetry by testing if the standardized
nonparametric skew (\frac{(Mean - Median)}{SD}) is different than 0.
This is an underlying assumption of Wilcoxon signed-rank test.
Usage
check_symmetry(x, ...)
Arguments
x
Model or numeric vector
...
Not used.
Examples
V <- suppressWarnings(wilcox.test(mtcars$mpg))
check_symmetry(V)
