xmu_get_CI: Look up and report CIs for free parameters

In umx: Structural Equation Modeling and Twin Modeling in R

Look up and report CIs for free parameters

Description

Look up CIs for free parameters in a model, and return as APA-formatted text string. If std are available, then these are reported.

Usage

xmu_get_CI(
  model,
  label,
  prefix = "top.",
  suffix = "_std",
  digits = 2,
  SEstyle = FALSE,
  verbose = FALSE
)

Arguments

model	an OpenMx::mxModel() to get CIs from
label	the label of the cell to interrogate for a CI, e.g. "ai_r1c1"
prefix	The submodel to look in (default = "top.")
suffix	The suffix for algebras when standardized (default = "_std")
digits	Rounding digits.
SEstyle	If TRUE, report "b(se)" instead of b CI95[l,u] (default = FALSE) If "mxSE" compute these.
verbose	= FALSE

Value

• the CI string, e.g. ".73[-.20, .98]" or .73(.10)
