unianova: Compute one-way ANOVAs

Description

Computes one-way ANOVAs for one group variable and specified test variables. If no variables are specified, all numeric (integer or double) variables are used. A Levene's test will automatically determine whether a classic ANOVA is used. Otherwise Welch's ANOVA with a (Satterthwaite's) approximation to the degrees of freedom is used.

Usage

unianova(data, group_var, ..., descriptives = FALSE, post_hoc = FALSE)

Value

a tdcmm model

Arguments

data

a tibble or a tdcmm model

group_var

group variable (column name)

...

test variables (column names). Leave empty to compute ANOVAs for all numeric variables in data.

descriptives

a logical indicating whether descriptive statistics (mean & standard deviation) for all group levels should be added to the returned tibble. Defaults to FALSE.

post_hoc

a logical value indicating whether post-hoc tests should be performed. Tukey's HSD is employed when the assumption of equal variances is met, whereas the Games-Howell test is automatically applied when this assumption is violated. The results of the post-hoc test will be added to a list column in the resulting tibble.

Examples

WoJ %>% unianova(employment, autonomy_selection, autonomy_emphasis)
WoJ %>% unianova(employment, descriptives = TRUE, post_hoc = TRUE)
if (FALSE) {
WoJ %>% unianova(employment)
}
