In jsakaluk/dySEM: Dyadic Structural Equation Modeling

A function that performs a score test for relaxing each invariance equality constraint between partners in a given dyadic SEM model.

Description

A function that performs a score test for relaxing each invariance equality constraint between partners in a given dyadic SEM model.

Usage

getConstraintTests(constrainFit, filterSig = FALSE)

Arguments

constrainFit	fitted lavaan model with dyadic invariance equality constraints
filterSig	logical indicating whether to filter for significant constraints (default is FALSE)

Value

a data frame with rows of equality constraints (now with readable param labels) and test statistic, df, and p for whether constraint worsens model fit

Examples

dvn <- scrapeVarCross(dat = commitmentM, x_order = "sip", x_stem = "sat.g",
x_delim2="_", distinguish_1="f", distinguish_2="m")

sat.resids.script <- scriptCFA(dvn, lvname = "Sat",
constr_dy_meas = c("loadings", "intercepts", "residuals"),
constr_dy_struct = "none")

sat.resids.mod <- lavaan::cfa(sat.resids.script, data = commitmentM, std.lv = FALSE,
auto.fix.first= FALSE, meanstructure = TRUE)

getConstraintTests(sat.resids.mod)
