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)
slope |
a matrix with items in the columns and slopes in the rows |
ogive |
the ogive constant (default rpf.ogive) |
\frac{\mathrm{slope}}{≤ft[ 1 + \mathrm{rowSums}(\mathrm{slope}^2) \right]^\frac{1}{2}}
a factor loading matrix with items in the rows and factors in the columns
Other factor model equivalence:
fromFactorLoading(),
fromFactorThreshold(),
toFactorThreshold()
