Hello Daniel, I have the same problem than you : i use nls.profile to compute confidence intervals of estimated parameters but it fails and stop... I tried to increase alphamax value as Douglas suggested that it should work but it's not... Did you find a method to tell nls.profile to ignore e

Hello, I use nls.profile to compute confidence intervals of parameter estimates of a non-linear model. When computing the profiles, the model function produces an error for certain parameter combinations. Therefore nls fails and so does nls.profile. Is there a way to tell nls.profile to ignore er
