how to set the starting value in lme
Hi,
When I fit the mixed-effects model by lme, I got the convergence error code = 1
message = iteration limit reached without convergence (9). Even after I increase the iteration numbers, it still did not work. The only way I found to avoid the error message is to increase the number of iterations for the EM algorithm, which need to be at least 1100. But the weird thing is that the correlation
