Items to be anchored can be entered interactively by setting IANCHQ=Y. If you specify this, you are asked if you want to anchor any items. If you respond "yes", it will ask if you want to read these anchored items from a file; if you answer "yes" it will ask for the file name and process that file in the same manner as if IAFILE= had been specified. If you answer "no", you will be asked to enter the sequence number of each item to be anchored, one at a time, along with its logit (or user-rescaled by USCALE= or UASCALE=) value. When you are finished, enter a zero.

 

Example: You are doing a number of analyses, anchoring a few, but different, items each analysis. You don't want to create a lot of small anchor files, but rather just enter the numbers at the terminal, so specify:

IANCHQ=Y

CONVERGE=L  ; only logit change is used for convergence

LCONV=0.005  ; logit change too small to appear on any report.

 

You want to anchor items 4 and 8.
