Dear Mike,
I am having some problems when fitting a path model in the second stage (Random Effects Model) which includes some indirect effects. In the documents attached you can find the data (.dat), the commands I used (.R) and the path model I would like to fit (.png).
The error that appears is the next one:
Error in $<-.data.frame
(*tmp*
, "Std.Error", value = NA) :
replacement has 1 row, data has 0
In addition: Warning messages:
1: In pchisq(tT, df = dfT, lower.tail = FALSE) : NaNs produced
2: In sqrt(max((tT - dfT)/(n - 1), 0)/dfT) : NaNs produced
Warning message:
In model 'TSSEM2 random effects model' NPSOL returned a non-zero status code 1. The final iterate satisfies the optimality conditions to the accuracy requested, but the sequence of iterates has not yet converged. NPSOL was terminated because no further improvement could be made in the merit function (Mx status GREEN).
Thanks in advance,
Belén.
