Warnings en GLMM (lme4)
...hora de la selección del modelo final.
El modelo me funciona, sin embargo me aparecen unos warnings que no sé a que se deben ni la importancia real en el cáculo de mi modelo. Mi pregunta es si alguien en el foro sabe porqué aparecen y como solucionarlos. Los warnings son:
Warning messages:
1: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
Model failed to converge with max|grad| = 0.00431561 (tol = 0.001, component 7)
2: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
Model is nearly unidentifiable: very large eigenvalue

identifying convergence or non-convergence of mixed-effects regression model in lme4 from model output
...nly output I saved were the inferential
statistics for my fixed and random effects. I did not save any output
related to the performance to the machine learning algorithm used to fit
the models (REML=FALSE). After running all the simulations, I got about
two dozen messages of this kind:
25: In checkConv(attr(opt, "derivs"), opt$par, ctrl =
