In semTools: Useful Tools for Structural Equation Modeling

Deprecated functions in package semTools.

Description

The functions listed below are deprecated and will be defunct in the near future. When possible, alternative functions with similar functionality are also mentioned. Help pages for deprecated functions are available at help("semTools-deprecated").

Usage

longInvariance(model, varList, auto = "all", constrainAuto = FALSE,
  fixed.x = TRUE, std.lv = FALSE, group = NULL, group.equal = "",
  group.partial = "", strict = FALSE, warn = TRUE, debug = FALSE,
  quiet = FALSE, fit.measures = "default", baseline.model = NULL,
  method = "satorra.bentler.2001", ...)

measurementInvariance(..., std.lv = FALSE, strict = FALSE, quiet = FALSE,
  fit.measures = "default", baseline.model = NULL,
  method = "satorra.bentler.2001")

measurementInvarianceCat(..., std.lv = FALSE, strict = FALSE,
  quiet = FALSE, fit.measures = "default", baseline.model = NULL,
  method = "default")

reliability(object, what = c("alpha", "omega", "omega2", "omega3", "ave"),
  return.total = FALSE, dropSingle = TRUE, omit.factors = character(0),
  omit.indicators = character(0), omit.imps = c("no.conv", "no.se"))

reliabilityL2(object, secondFactor, omit.imps = c("no.conv", "no.se"))

Previous measurement-invariance functions

The measurementInvariance, measurementInvarianceCat, and longInvariance functions will no longer be supported. Instead, use the measEq.syntax function, which is much more flexible and supports a wider range of data (e.g., any mixture of numeric and ordered indicators, any combination of multiple groups and repeated measures, models fit to multiple imputations with runMI).

Reliability

The original reliability function was suboptimally designed. For example, AVE was returned, which is not a reliability index. Also, alpha and several omega-type coefficients were returned, including the original formula that was in appropriate for models with complex structure. Some features could be controlled by the user for one but not both types of index For example, alpha for categorical indicators was returned on both the observed and latent-response scales, but this was not an option for any omega-type indices. The omegas differed in terms of whether the observed or model-implied covariance matrix was used in the denominator, but alpha was only computed using the observed matrix. These inconsistencies have been resolved in the new compRelSEM function, which returns only one reliability index (per factor, optionally total score) according to the user's requested features, for which there is much more flexibility. Average variance extracted is now available in a dedicated AVE function.

Higher-Order Reliability

Originally, composite reliability of a single higher-order factor was estimated in a separate function: reliabilityL2. It is now available for multiple higher-order factors in the same model, and from the same compRelSEM function that estimates reliability for first-order factors, using the higher= argument to name higher-order factors in the fitted model.
