In tbates/umx: Structural Equation Modeling and Twin Modeling in R

FIML-based trio-based polychoric, polyserial, and Pearson correlations

Description

Compute polychoric/polyserial/Pearson correlations with FIML in OpenMx.

Usage

umx_polytriowise(
  data,
  useDeviations = TRUE,
  printFit = FALSE,
  use = "any",
  tryHard = c("no", "yes", "ordinal", "search")
)

Arguments

data	Dataframe
useDeviations	Whether to code the mode using deviation thresholds (default = TRUE)
printFit	Whether to print information about the fit achieved (default = FALSE)
use	parameter (default = "any")
tryHard	'no' uses normal mxRun (default), "yes" uses mxTryHard, and others used named versions: "mxTryHardOrdinal", "mxTryHardWideSearch"

Value

- matrix of correlations
