In visStatistics: Automated Selection and Visualisation of Statistical Hypothesis Tests

Test normality using pooled standardized residuals

Description

Standardizes values within each group and applies a single normality test to the pooled standardized values. This avoids multiple testing issues when deciding between parametric and non-parametric methods.

Usage

pooled_normality_test(y, g, test = c("shapiro", "ad"), min_n = 3L)

Arguments

y	Numeric vector of response values
g	Factor or vector defining groups (must have at least 2 levels)
test	Character, either "shapiro" or "ad" for Anderson-Darling
min_n	Minimum sample size per group required (default 3)

Value

A list with test results (statistic, p.value, method, data.name)
