Hi:
I'm using function lmer from package lme4, and I get this message:
" There were 12 warnings (use warnings() to see them)"
So I checked them:
Warnings 1 to 11 said:
1: optim returned message ERROR: ABNORMAL_TERMINATION_IN_LNSRCH
in: "LMEoptimize<-"(`*tmp*`, value = structure(list(maxIter = 50, ...
and Warning 12 said:
12: IRLS iterations for glmm did not converge in: lmer(Enfermo ~ Bloque +
Trat * Var * dia + (1 | IDfruto), data = desinf, ...
There was no error message in the call of lmer function, so:
What do these warnings mean?
Do these errors occur at earlier iterations but finally the model converges?
Can the model I got be trust?
Thanks, Gabriela.
PD: I'm using:
Windows XP ,
R 2.1.0,
Package lme4, version 0.95-6
And the fitted model was:
modelo1 <- lmer(Enfermo ~ Bloque+Trat*Var*dia+(1|IDfruto),
data=desinf,
subset=!desinf$dia==1&!desinf$Trat=="Sin_inoculo",
family=binomial)
