Tests and visualizes normality assumptions for numeric variables using Shapiro-Wilk test, skewness, kurtosis, and Q-Q plots.

Usage

normality_check(data, Vars, tests = TRUE, plots = TRUE, digits = 3)

Arguments

data

A data frame containing the variables.

Vars

Character vector of numeric variable names to check.

tests

Logical. Perform normality tests? Default TRUE.

plots

Logical. Create Q-Q plots? Default TRUE.

digits

Integer. Number of decimal places. Default 3.

Value

A list containing:

• table: A gt table with normality statistics

• plots: Q-Q plots (if requested)

• results: Data frame with all statistics
