toFactorLoading function

Convert response function slopes to factor loadings

Convert response function slopes to factor loadings

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

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 )

Returns

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

Details

slope[1+rowSums(slope2)]12 \frac{\mathrm{slope}}{\left[ 1 + \mathrm{rowSums}(\mathrm{slope}^2) \right]^\frac{1}{2}}
