lme convergence failure within a loop
...structure, across a spatial grid with data points collected at various
time points within each grid cell. I'm trying to use a 'for' loop to try
the model fit on each grid cell. In some cells lme does not converge,
giving me the error:
Error message: In lme.formula(logarea ~ year + summ_d, data = grid2,
random = ~year + :
nlminb problem, convergence error code = 1
message = iteration limit reached without convergence (9)
When I get the error, the program aborts, and my loop stops.
I'm not too worried about the error, as a generic mixed model structure
may not be the b...
