Hello,
I am having issues pooling correlation matrices with random effects. I have results from a total of ~30 studies I plan to pool. At this stage, I am trying to pool 11 of these to test things out, but when I run tssem the model never converges.
There are a few possible issues I'm wondering about. These are very large correlation tables (i.e., many variables) and none of the data sets include all correlations (but every cell has data from at least one study), thus there are many NAs, and I wonder whether the software is just having difficulty with estimation. I also wonder whether there are too few studies to estimate the random effects for so many correlations. This is also my first time attempting MASEM, so I may have very well made a simple coding error that I'm missing.
I would appreciate any help with this. The code and data files are attached. Please let me know if there are any problems loading the files or if any clarification is needed.
Thank you,
Whitney
