Dear All
I have a table (output from sas) about few items. Using Item response theory model (IRT) I estimated the parameters for all item as well as their standard error. I interprated the table. But I need extra help in interpretation regarding some of unusual value. I need an expert in the field (with knowledge in Item Response Theory (IRT) and differential item functioning (DIF)) to help me.
Please notice that after helping me with this, I have other stuff that i need help in the same field.
Please, do not change you price after the bidding and agreement.
