Hello,
I am using ConQuest version 4.2.5 and every time I try to run a DIF analysis it crashes.

Can you create a small working example to replicate the problem?

Hi Jane,
You are referring to the Mantel Haenszel (MH) command. This is an issue and I've alerted Ray on this.
MH is a classical approach to DIF analysis. As an alternative, have you considered an IRT approach? There is a tutorial on this on the website (Tutorial 6).

Cheers,
