I am running a Item Response Theory Analysis of a patients' satisfaction survey. I use a graded response model.
This is the code:
Title 'IRT - Satisfaction Scale - Form1: Unidimensional';
proc irt data=[data] plots=(all) ;
var q24 q17 q20 q25 q19 q22 q27 q11;
I call the plots for Item information and test information functions but I would also like to know the exact estimates of the max information and location parameters of such curves (either in table format or superimposed in the graph). I cannot find a way to call this output in PROC IRT. Could you please help me?
Thanks in advance,
