norm_test_fun {analyzer}

Checks for Normality Assumption

Description

norm_test_fun checks for the normality assumption

Usage

norm_test_fun(x, method = "anderson", pval = 0.05, xn = "x", bin = FALSE)

Arguments

x

a numeric vector

method

shapiro for Shapiro-Wilk test or 'anderson' for 'Anderson-Darling' test of normality or ks for 'Kolmogorov-Smirnov'

pval

significance level for normality tests. Default is 0.05

xn

vector name

bin

TRUE if only TRUE/FALSE is required

Details

This function checks for normality assumption using shapiro, Kolmogorov-Smirnov or Anderson Darling test. If the parameter bin is TRUE, then TRUE is returned if vector is normal, otherwise FALSE. The significance level is passed through the parameter pval

Value

Logical TRUE/FALSE based on the performed test and pval. If the vector follows the normality assumption, then TRUE is returned
