MRANGE= half-range of measures on plots = 0, auto-size

Specifies the measure half-range, (i.e., range away from the origin or UMEAN=), of the maps, plots and graphs. This is in logits, unless USCALE= is specified, in which case it must be specified in the new units defined by USCALE=. To customize particular tables, use the Specification pull-down menu, or see TFILE=.

 

Example 1: You want the vertical range on the Table 1 map to be -5 to +5
MRANGE=5

 

Example 1: You want to see the category probability curves in the range -3 to +3 logits:
  MRANGE=3

 

Example 2: With UMEAN=500 and USCALE=100, you want the category probability curves to range from 250 to 750:
UMEAN=500 ; item mean calibration
USCALE=100 ; value of 1 logit
MRANGE=250 ; to be plotted each way from UMEAN=
