Dear all, I have pooled data stemming from two cross-sectional surveys (with independent respondents, Firebaugh 1997)and want to estimate a path model for four variables using Mplus. However, yet I haven't found any article applying SEM to repeated CS surveys - thus it would be extremely helpful if you could tell me 1. if such an analysis could, in principle, be conducted at all 2. Mplus has specific defaults to be considered 3. point to related literature applying SEM for repeated cross-sectional data
My situation is similar to Elmar, only a little bit more complicated. I am testing a path analysis using a HUGE repeated complex sample dataset (Cross-Sectional). The problem is that the individual respondents are different from year to year, and only the group/organisational level can be possibly matched up.
The fit indices are very good for 3 repeated models (TYPE=TWOLEVEL MISSING). However, the parameters vary to some extent, especially on BETWEEN level.
How could we possibly take advantages of repeated data (on between level only) to explain the changes?
Is that possible to compare means and parameters on between level from three years model to explain the change curve over time? How robust it would be?
Also, if I draw path diagram, which coefficient should I put in, std or stdYx?
Many thanks in advance.
(Survey was conducted in more than 500 healthcare organisations in UK, with more than 200,000 respondents annually.)
It sounds like you have the same organizations over time but different individuals from the organization and you want to create a data set where organization is the analysis unit using the average over the individuals at each year as the organization's data points. I think that is a little shaky given that the data points from each year comes from different individuals who are very likely not randomly selected. You may be criticized for this.
I'm sorry but I think you may have misunderstood me. My point is that using data where different subjects are observed at each time point to estimate a repeated measures model is not definsible in my opinion.
Yes. I did understand your points. Strictly speaking, it is not a repeated survey, isn't it?
However, our concerns are mainly on the organisational level rather than individual level. Is there any way to work it around? Or alternatively, you would suggest to take annually survey separately, rather than messing them up.
