General
1

m0.qp <- glmer(Case ~ 1 + (1 | Villages), data = df.final4, family = poisson())

m1.qp <- update(m0.qp, .~.+ REACT2 + Time + Time*REACT2 +Nb.consult:REACT2 + Nb.consult + Temp.Max + Humidity.Mean + Pluv.Mean)
Warning messages:
1: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
Model failed to converge with max|grad| = 0.00397246 (tol = 0.002, component 1)
2: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
Model is nearly unidentifiable: very large eigenvalue
