**Questions and Answers / Re: Obtain Fit Statistics Like in Quest**

Hi Juliane,

the output from the pfit does not include standard errors, and therefore also does not include t values.

It is relatively easy to add them in and I have put them on the work agenda for a future release of ConQuest.

Note that person fit statistics will generally be estimated relatively poorly (we tend to have fewer items per person, than vice-versa) and the t values may not be very useful. It may be more interesting to look at some visualisations - for example a qqplot of the quantiles of the pfits versus the quantiles of the std normal distribution. This will tell you if you have strong departure from the expectation.
