I have a set of categorical(binary) data, but I don't know whether ex5.2 or ex5.5 should I use? What's the difference between the two analysis method(ex5.2 & ex5.5)? Do they have different link function assumption?
I am using CFA with WLSMV and if I'm correct, theoretically I am carrying out an IRT. Because I use mac, I do not get the plots of the estimated model. However, I also do not get any information on the item discrimination and item difficulties in the output. Is this due to having mac or something missing in my input:
