I am working with the latest version of lme4 and having a great deal of difficulty specify control parameters (specifically, iterations and convergence criteria). I have been using variants of the following, with no success:
The usable arguments in optCtrl vary according to which optimizer you have
chosen:
glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
family = binomial, data = cbpp,
control=glmerControl(optimizer="Nelder_Mead",
optCtrl=list(FtolAbs = 1e-2, iprint=1),
boundary.tol = 1e-2))
load(optimx)
glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
family = binomial, data = cbpp,
control=glmerControl(optimizer="optimx",
optCtrl=list(method="nlminb", trace=1, kkt=FALSE),
boundary.tol = 1e-2))
