Hi all,
Thank you for this wonderful software and very useful forum for running metaSEM. I'm new to both R and metaSEM, but I've generally found it to be relatively straightforward with all the great resources available.
There are a pair of metaSEM models I'm running that have been giving me two separate error messages that I can't wrap my head around. These occur when running the Stage 1 portion of the script:
-
Error: The observed covariance matrix is not a symmetric matrix
(This seems akin to problems described here [https://openmx.ssri.psu.edu/thread/1039] where values estimated at, say, the 16th decimal point end up being slightly different above/below the diagonal. The fix seems to simply be to round numbers, but I'm not sure how to access the guts of the metaSEM package to do this). -
Error in lambda[length(lambda)]/lambda[1] > tol :
invalid comparison with complex values
(I'm not sure what this means).
Also, just to be clear, I don't receive both of these messages at the same input matrices but rather on separate metaSEMs I'm running. Any ideas? Thanks!
