Normality test of a numeric vector

Applies a Shapiro-Wilks test to a numeric vector, and returns a list with the statistic W, its p-value, and a character string with the interpretation.

Usage

residuals_test(residuals)

Arguments

residuals

Numeric vector, model residuals.

Value

A list with four slots:

• /item w W statistic returned by shapiro.test(). /item p.value p-value of the Shapiro test. /item interpretation Character vector, one of "x is normal", "x is not normal". /item plot A patchwork plot with the qq plot and the histogram of x.
