toFactorLoading {rpf}

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
