Confirmatory Factor Analysis (groupwise) — cfa

This function will run N number of CFA where N = length(group), and report the fit measures of CFA in each group. The function is intended to help you get a better understanding of which group has abnormal fit indicator

cfa_groupwise(data, ..., group, model = NULL, ordered = FALSE)

Arguments

data: data frame
...: CFA items. Support dplyr::select() syntax.
group: character. group variable. Support dplyr::select() syntax.
model: explicit lavaan model. Must be specify with model = lavaan_model_syntax.
ordered: logical. default is FALSE. If it is set to TRUE, lavaan will treat it as a ordinal variable and use DWLS instead of ML

Value

a data.frame with group-wise CFA result

Details

All argument must be explicitly specified. If not, all arguments will be treated as CFA items
