umxRotate.MxModelCP: Rotate a CP solution

In umx: Structural Equation Modeling and Twin Modeling in R

Rotate a CP solution

Description

Rotate a CP solution. Should work with rotations provided in library("GPArotation") and library("psych"), e.g

Orthogonal: "varimax", "quartimax", "bentlerT", "equamax", "varimin", "geominT" and "bifactor"

Oblique: "Promax", "promax", "oblimin", "simplimax", "bentlerQ", "geominQ", "biquartimin" and "cluster"

Usage

## S3 method for class 'MxModelCP'
umxRotate(
  model,
  rotation = c("varimax", "promax"),
  tryHard = "yes",
  freeLoadingsAfter = TRUE,
  verbose = TRUE
)

Arguments

model	a umxCP() model to rotate.
rotation	name of the rotation.
tryHard	Default ("yes") is to tryHard.
freeLoadingsAfter	return the model with factor loadings free (default) or fixed in the new locations.
verbose	print detail about the rotation

Details

This works by taking the common-pathways loadings matrix from a solved umxCP() model, rotating these, placing them back into the loadings matrix, re-estimating the model with the parameters fixed at this rotation, then return the new model.

Value

• Rotated solution.
