I am using the BootMer function for current research, and have a question regarding a specific warning message. When the message below appears, does BootMer recalculate the nonconvergent iteration, use an estimate from the nonconvergent iteration, or pass over the nonconvergent iteration?
Warning messages:
1: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
unable to evaluate scaled gradient
2: In checkConv(attr(opt, "derivs"), opt$par, ctrl = control$checkConv, :
Model failed to converge: degenerate Hessian with 1 negative eigenvalues
Thank you for your time.
Regards,
Malcolm Wolff
