Is there any way to calculate the standard error of the covariances/correlations of the dimensions? In the .shw file, only the variances' standard errors are shown, but not the covariances'. Thanks!

Hi, I hope you can help me with this.

In running the .cqc file on the .dat file attached, ConQuest doesn't use all the cases on each item. For example, the first item has 5280 responses but the output .itn file shows 3184 cases. All the 8839 cases were read in as the screen (while invoking the .cqc file) shows. Also, the total N at the end of the .itn file shows 26733 and I was puzzled by that number. Thanks so much!

I am using a Mac version of ConQuest:
Version: 4.15.0
Professional Build:  Oct  3 2017


Is there a way to let ConQuest estimates wle for cases with already (previously) estimated .prm files, without re-estimating the item parameters? If you have done so, would you mind sharing the commands you used to do this? thanks much!

Questions and Answers / softkey
« on: April 06, 2019, 11:33:41 PM »

I recently purchases the extension version of ConQuest to run with more than 3000 cases. But every time I run ConQuest I have to "set softkey= ...". Is there a way to make the key stick so I don't have to set it every time? Thank you so much for your help!

ConQuest crashed with a "Segmentation fault: 11" when executing the Kidmap command. What could this fault be caused by? Thanks!

Questions and Answers / multidimensional run error
« on: February 26, 2019, 12:03:53 AM »
I hope somebody can help me identify the problem with my command file. I was trying to run a 4-dimensional analysis on a test with 25 items. Here is my .cqc file:

Datafile scotid6m.dat;
Format responses 1-25;
Labels << scotid6.lab;
score (0,1) (0,1) ( ) ( ) ( ) ! items (5, 23);
Score (0,1) ( ) (0,1) ( ) ( ) ! items (4);
Score (0,1) ( ) ( ) (0,1) ( ) ! items (1, 6-13, 16-20, 24-25);
Score (0,1) ( ) ( ) ( ) (0,1) ! items (2-3, 14-15, 21-22);
Model item;
Show !estimates=latent >> scotid6mMD.shw;
Itanal >> scotid6m.itn;
Show cases !estimates=eap >> scotid6mMD.eap;
Show cases !estimates=mle >> scotid6mMD.mle;
after submitted to conquest, I got this error message: "The number of items scored does not match the number that are defined". I have run a unidimensional analysis with this same .dat and .lab files without any problem. Help!
Thanks much!
