convergence

Update on context:
Aim: estimating the association between (1) responses accuracy and (2)
time, groups, and 7 word-covariates.

I included 2 covariates in the interactions with group & Time.
Number of observations : 5800

glmer(
  *Response* ~ Characters + Band_freq + Imageability + Cognateness +
Syllables + *Group*Time*PoS* + *Group*Time*Verbal_freq *
+ (Time|Subject) + (Time| Word),
glmerControl(optimizer="bobyqa", optCtrl = list(maxfun = 2e5)), data =
written.Form.data
  family = 'binomial'
