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

Create a matrix of correlations for variables of diverse types (binary, ordinal, continuous)

Description

umxHetCor is a helper to:

1. return just the correlations from John Fox's polycor::hetcor function

2. If you give it a covariance matrix, return the nearest positive-definite correlation matrix.

Usage

umxHetCor(
  data,
  ML = FALSE,
  use = c("pairwise.complete.obs", "complete.obs"),
  treatAllAsFactor = FALSE,
  verbose = FALSE,
  return = c("correlations", "hetcor object"),
  std.err = FALSE
)

Arguments

data	A data.frame() of columns for which to compute heterochoric correlations. OR an existing covariance matrix.
ML	Whether to use Maximum likelihood computation of correlations (default = FALSE)
use	How to handle missing data: Default= "pairwise.complete.obs". Alternative ="complete.obs".
treatAllAsFactor	Whether to treat all columns as factors, whether they are or not (Default = FALSE)
verbose	How much to tell the user about what was done.
return	Return just the correlations (default) or the hetcor object (contains, method, SEs etc.)
std.err	Compute the SEs? (default = FALSE)

Value

• A matrix of correlations
