HIADJ= correction for top rating (or partial credit) scale categories = 0.25 |
Top Up Down
A A |
The Rasch model models the measure corresponding to a top 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 top category. This is the measure corresponding to an imaginary rating HIADJ= rating points below the top category. The corresponding instruction for the bottom category is LOWADJ=.
Example: The standard spread in Table 2.2 is based on HIADJ=0.25. You wish the top category number to be printed more to the right, further away from the other categories.
HIADJ=0.1
