mirt (version 1.17.1)

summary-method: Summary of model object

Description

Transforms coefficients into a standardized factor loading's metric. For MixedClass objects, the fixed and random coefficients are printed.

Usage

## S3 method for class 'SingleGroupClass':
summary(object, rotate = "oblimin",
  Target = NULL, suppress = 0, digits = 3, verbose = TRUE, ...)

Arguments

object

an object of class SingleGroupClass, MultipleGroupClass, or MixedClass

rotate

a string indicating which rotation to use for exploratory models, primarily from the GPArotation package (see documentation therein).

Rotations currently supported are: 'promax', 'oblimin', 'varimax'

Target

a dummy variable matrix indicting a target rotation pattern. This is required for rotations such as 'targetT', 'targetQ', 'pstT', and 'pstQ'

suppress

a numeric value indicating which (possibly rotated) factor loadings should be suppressed. Typical values are around .3 in most statistical software. Default is 0 for no suppression

digits

number of significant digits to be rounded

verbose

logical; allow information to be printed to the console?

...
