lr_test: Conduct Likelihood Ratio tests

In tidySEM: Tidy Structural Equation Modeling

Conduct Likelihood Ratio tests

Description

For a multigroup model of class MxModel, conduct overall and pairwise likelihood ratio tests. All submodels must be identical.

Usage

lr_test(x, compare = c("All", "A", "S", "F", "M", "Thresholds"), ...)

Arguments

x	An object for which a method exists.
compare	Character vector, indicating which matrices to constrain to be equal in pairwise comparisons.
...	Additional arguments passed to other functions.

Value

An object of class lr_test and list.

Examples

if(requireNamespace("OpenMx", quietly = TRUE)){
df <- iris[c(1:10, 140:150), c(1, 5)]
names(df) <- c("x", "group")
mod <- as_ram("x~1", data = df, group = "group")
mod <- run_mx(mod)
lr_test(mod)
}
