Hi,
There is a warning about my starts value.
2 perturbed starting value run(s) did not converge.
WARNING: WHEN ESTIMATING A MODEL WITH MORE THAN TWO CLASSES, IT MAY BE
NECESSARY TO INCREASE THE NUMBER OF RANDOM STARTS USING THE STARTS OPTION
TO AVOID LOCAL MAXIMA.
it led to
WARNING: THE BEST LOGLIKELIHOOD VALUE WAS NOT REPLICATED IN 1 OUT OF 1
BOOTSTRAP DRAWS. THE P-VALUE MAY NOT BE TRUSTWORTHY DUE TO LOCAL
MAXIMA. INCREASE THE NUMBER OF RANDOM STARTS USING THE LRTSTARTS OPTION.
How to choose right starts value to avoid local maxima?
Thank you.

And I increased the number of starts(4 LRTSTARTS are maximum).

Nothing but only this warning showed. Is results trustable with this warning? No other warning about BLRT.
