Creating 'itemresponseplot' after LCA

VKWS — Mon, 28 Feb 2022 22:31:10 GMT

Hello, I am using PROC LCA function and I would like to create an item response plot. I followed user's guide "SAS Graphics Macros for Latent Class Analysis", but I am not sure what is wrong in order to create an item response plot. I downloaded the Macro function from https://scholarsphere.psu.edu/resources/c3072c06-52ba-464b-9237-351857846b44 (LcaGraphicsV2.zip )

This is my first time using Macro function and I think the problem probably coming there but I have no clue where is the problem. I would appreciate some direction. Below was the code I used.

%INCLUDE "C:\Program Files\SASHome\xxx\macro\LcaGraphicsV2.sas";

PROC LCA DATA=combined1 OUTPARAM=param3 OUTPOST=test3 OUTEST=est3 OUTSTDERR=std3 OUTSEEDs=;
	id idxx;
 	NCLASS 3;
	ITEMS surveyq2 surveyq3 surveyq4 surveyq5 surveyq6 surveyq7 surveyq8 ;
	CATEGORIES  4 4 4 4 4 4 4;
	SEED 100000;
	NSTARTS 20;
RUN;

%ItemResponsePlot(ParamDataset=param3);

Hello,

If I look at this paper :

Paper 5500-2016
Latent Class Analysis Using PROC LCA
Patricia A. Berglund, University of Michigan

https://support.sas.com/resources/papers/proceedings16/5500-2016.pdf

, your calling of the macro seems correct (on the condition that it was defined and compiled of course).

Use the options

options mprint symbolgen mlogic source2;

and run again.
Then you get additional log on what may be wrong.

Please note PROC LCA itself is a user-defined procedure not officially supported by SAS.

Cheers,

Koen
