I need to perform a longitudinal path analysis among 7 variables that were collected at ten different time points (70 variables +covariates in a wide format). The path diagram is as follows:

I like to do something similar like the following image extracted from the video 'The SEM Approach to Longitudinal Data Analysis Using the CALIS Procedure':

In above picture, anxiety is the outcome variable. My question is: If I were to fit a linear latent curve model using proc calis, where would I provide all my predictor variables?

Thanks!

Hello @Sudeep_Neupane ,

 

Have you seen :

 

SAS Global Forum proceedings 2015 -- Paper SAS1745-2015
The SEM Approach to Longitudinal Data Analysis Using the CALIS Procedure
Xinming An and Yiu-Fai Yung, SAS Institute Inc.
Qing Yang, Duke University
https://support.sas.com/resources/papers/proceedings15/SAS1745-2015.pdf

?

 

The paper covers basic latent curve models!

 

Thanks,

Koen

Hello, Mr. Koen,
Thank you very much for pointing that out to me. The screenshot of the above code is extracted from the specific paper that you have mentioned here. I tried to reach one of the authors via LinkedIn too, however, I haven't heard back. Apparently, there are not many resources on path analysis + longitudinal data that I know of. I am basically stuck in two concepts: 1) How do I define paths if I include all the individual variable at one specific time point in the lineqs statement? OR, 2) How do I define "time" if I transform wide data into long format into the path statement.

Hello @Sudeep_Neupane ,

 

I have sent a SAS-internal mail to Yiu-Fai Yung.

I think Xinming An no longer works at SAS (?).

 

Let's see if he responds.

 

Have a nice weekend,

Koen

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
