uve:Mike,Thanks again. All worked out well. I was shocked to see that for each of the models, except one, only three different point observations were assigned by the judges.

Mike.Linacre:Chris, the non-extreme computation looks correct. The computation with extremes is definitely incorrect.The measures corresponding to extreme scores should be the most extreme. Their standard errors should be the highest.Example file lfs.txt. The rating scale is 0,1,2. There are 25 items. So the maximum score is 50:1 Child T.Score T.Count Obs.Avge FairMAvge Measure S.E.

Gloria:Hi MikeThanks so much for your soon reply and your priceless help.I checked the help menu (help SAFILE=) and found Example 5 really helpful. Applying this example to my Math test, I am planning to include this in my control file (the example only use 6 items just to simplify, actually my test has more items), but I still have one doubt that I detail below:ISGROUPS=00111IREFER=BBAAAIVALUEA=0100IVALUEB=0120IAFILE=*p1 -.51p2 -.22p3 -1.49p4 -1.27p5 -.86*SAFILE=*p1 1 -1.51p1 2 -.73p2 1 -2.53p2 2 -1.85*But my doubts are:(1) The Winsteps example 5 (SAFILE= help) confused me a bit, because in that example, only SAFILE is used to anchor a partial-scale item. Since you mentioned in your previous note that I have to use both IAFILE and SAFILE to anchor partial-credit item, I 'd appreciate if you let me know if I am in the right track in the example described above.(2) The measure of the categories 1&2 for the items 1&2 came from WinSteps table 3.2 (Structure measure), but there is no value for category 0. Should I anchor category zero equal to zero in the SAFILE? (I saw some examples in the help menu that did this but it is not clear for me why).Thanks in advance for your helpG
Mike.Linacre:Gloria, you are doing well :-) Example 5 is clearer.1. Please use the item entry numbers, not the item labels. 1 instead of p1.2. the SAFILE= values are relative to the IAFILE= values, so usually IAFILE= are required (unless the item difficulties are being re-estimated).3. the lowest category is anchored at 0 as a place-holder, so that Winsteps knows that it is part of the anchored partial credit structure.IAFILE=*1 -.512 -.223 -1.494 -1.275 -.86*SAFILE=*1 0 01 1 -1.511 2 -.732 0 02 1 -2.532 2 -1.85*
1.27.0.1406 03/02/2010 Fixed BP error on PathAtom retrieval from sql tables. Fixed User Not detected for MD3 version (Panel would not display patient) when the user had been added through MD3 Add user and therefore no Initial ID assigned. Added Scores output to questionnaire forms in PCD.
In addition to the Service page, Internet Service Manager's ServiceProperties sheet includes Directories, Logging, and Advanced pages. (Microsofthasn't replaced directory with folder in all instances.)The Directories page displays Web-related subfolders of the \inetsvr folder,including Web-style share names, such as /Scripts, in the Alias column(see fig. 1.27). The Logging page allows you to log user statistics toa text file or to a SQL Server 6.x database (see fig. 1.28) or any otherODBC-compliant RDBMS. Before specifying the logging database in the Loggingpage, you need to create the ODBC database and add a System data sourcefor the database with Control Panel's ODBC tool. The Advanced page allowsyou to specify TCP/IP clients to be excluded from intranet access; alternatively,you can specify the TCP/IP address of each client with intranet access. 2ff7e9595c
