UANCHOR= anchor values supplied in user-scaled units = Yes |
For backwards compatibility only.
UANCHOR= simplifies conversion from previously computed logit measures to user-scaled measures.
If UASCALE<>0.0 then UANCHOR=A is forced.
If UASCALE=0.0 then UANCHOR=N is forced.
UANCHOR=A or N or L specifies that the anchor values are in UASCALE= units per logit. Reported measures will be user-rescaled by UMEAN= (or UIMEAN= or UPMEAN=) and USCALE=.
Logit measure = anchored measure/UASCALE - UMEAN/USCALE
UANCHOR=Y specifies that anchor values are in USCALE= units per logit.
Example 1: Your item bank calibrations are user-scaled with 10 units per logits, but you want to report person measures in CHIPS (BTD p.201):
UASCALE=10 ; user-scaling of anchor values
UANCHOR=A
USCALE=4.55
Example 2: Your previous test was in logits, but now you want the user-scaling 100 per logit.
UASCALE=1 ; user-scaling of anchor values: logits
UANCHOR=Logits
USCALE=100
