Specifies the number of units per logit of the anchor values.

UASCALE=0 - the anchor values are in the current output scale

UASCALE= other value - this is the units per logit of the anchor values.

UIMEAN= and UPMEAN= are ignored when there are anchor values.

Example 1: The anchor values are user-scaled such that 1 logit is 45.5 units, so that differences of -100, -50, 0, +50, +100 correspond to success rates of 10%, 25%, 50%, 75%, 90%:

UASCALE = 45.5

; 1 logit = 45.4 user-units

Example 2: The anchor values are on one scaling, but you want the reported values to be on another scaling.

UASCALE= 5

; there are 5 units per logit in the scaled values

USCALE=10        

; you want 10 units per logit on the reported values

Example 3: The anchor measures are in logit scaling, the output measures are to be in user-scaling

UASCALE = 1

; anchor values in logits

USCALE = 30

; 30 user-units per logit

Example 4: Anchor measures are in same scaling as the output measures

UASCALE = 0

; the default value

USCALE = user-value

; also used for anchor values
