LOWADJ= correction for bottom rating (or partial credit) scale categories = 0.25

The Rasch model models the measure corresponding to a bottom rating (or partial credit) scale category as infinite. This is difficult to think about and impossible to plot. Consequently, graphically in Table 2.2 and numerically in Table 3.1 a measure is reported corresponding to a bottom category. This is the measure corresponding to an imaginary rating LOWADJ= rating points above the bottom category. HIADJ= is the corresponding instruction for top categories. For choice of value, see EXTRSCORE=

 

Example: The standard spread in Table 2.2 is based on LOWADJ=0.25. You wish the bottom category number to be printed more to the right, close to the other categories.

LOWADJ=0.4
