umxReduceGxE: Reduce a GxE model.

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

Reduce a GxE model.

Description

This function can perform model reduction for umxGxE() models, testing dropping a⁠,c⁠ & e⁠, as well as c & c⁠, a & a' etc.

It reports the results in a table. Set the format of the table with umx_set_table_format(). Or set report = "html" to open a table for pasting into a word processor.

In addition to printing a table, the function returns the preferred model.

Usage

umxReduceGxE(
  model,
  report = c("markdown", "inline", "html", "report"),
  intervals = TRUE,
  baseFileName = "tmp_gxe",
  tryHard = c("yes", "no", "ordinal", "search"),
  silent = FALSE,
  ...
)

Arguments

model	A umxGxE() to reduce.
report	How to report the results. default = "markdown". "html" = open in browser.
intervals	Recompute CIs (if any included) on the best model (default = TRUE)
baseFileName	(optional) custom filename for html output (default = "tmp").
tryHard	Default ('no') uses normal mxRun. "yes" uses mxTryHard. Other options: "ordinal", "search"
silent	Default (FALSE)
...	Other parameters to control model summary.

Value

best model
