Hello everyone!
I calculated a Latent Class Analysis with JMP in the context of an validation of a questionnaire. A three class solution revealed to fit the data best. Now I have to display the “conditional item probabilities” or also called “in class probabilities” in a graphic. The aim is to obtain a graph where the individual items of the questionnaire are located on the X axis (a total of 23 items) and where the probability of affirming the item in dependence of the cluster (1/2/3) is located on the Y axis.
I will attach two screenshots of graphics I found that are exactly what I am aiming for with my dataset.
In one of the![LCA1.JPG LCA1.JPG](https://community.jmp.com/t5/image/serverpage/image-id/12322iB5AB9F9511DE35F7/image-size/large?v=v2&px=999)
two screenshots conditional item probabilities are marked in gray in case of differing significantly between the different classes (in case of differing at least 30% or more)---- would be great if anyone knows how to include this!
Who can help me? Since it is relatively urgent, I am happy about any idea!
Thanks a lot, best regards
Anne My
