toFactorLoading: Convert response function slopes to factor loadings

In rpf: Response Probability Functions

Convert response function slopes to factor loadings

Description

All slopes are divided by the ogive constant. Then the following transformation is applied to the slope matrix,

Usage

toFactorLoading(slope, ogive = rpf.ogive)

Arguments

slope	a matrix with items in the columns and slopes in the rows
ogive	the ogive constant (default rpf.ogive)

Details

\frac{\mathrm{slope}}{\left[ 1 + \mathrm{rowSums}(\mathrm{slope}^2) \right]^\frac{1}{2}}

Value

a factor loading matrix with items in the rows and factors in the columns
