convergence error code in mixed effects models
...,outer=~treat,test)
> model<-lme(leaf~treat,random=~leaf|rep)
Error in lme.formula(leaf~ treat, random = ~week|rep)
:
nlminb problem, convergence error code = 1;
message = iteration limit reached without convergence
(9)
Has anybody an idea to solve this problem?
Thanks

mixed-effects model with two fixed effects: interaction
Dear all,
In a greenhouse experiment we tested performance of 4 different species (B,H,P,R) under 3 different water levels in 10 replications. As response variable e.g. the number of emerging sprouts were measured on three dates. A simple Anova considering every measurement date separately shows a higly significant effect of species and moisture (and partly the interaction of both). The
