Computes various metrics of measurement invariance distances

Computes various metrics of measurement invariance distances

Usage

getMetrics(
  data,
  group,
  model,
  ...,
  metric = c("covariance", "correlation", "fit", "parameters")
)

Arguments

data

Individual data

group

Character. Grouping variable

model

lavaan model syntax

...

Additional arguments passed to incrementalFit or mgcfaParameters

metric

Character. Metric to be computed. One of "covariance", "correlation", "fit", or "parameters".

Value

Depending on the value of `metric` argument, returns:

• "covariance": covariance matrices across groups (output of computeCovariance)

• "correlation": correlation matrices across groups (output of computeCorrelation)

• "fit": pairwise decreases in fit indices (output of incrementalFit)

• "parameters": pairwise differences in parameters (output of mgcfaParameters)
