WebDec 22, 2024 · I think the profiling is failing on confint () for the Age variable. There's a diagnostic plot for the profile that you can do, showing the parameter tau for each coefficient. It has to span a wide enough range (given a specific confidence interval requested, like 0.95 or 0.9 etc) or else the interval can't be calculated. WebIt looks like what you have done in the second method is to have computed confidence intervals for the regression coefficients, then transformed those to obtain CIs for the predictions. This ignores the covariances between the regression coefficients.

Webconfint.univariateML Confidence Intervals for Maximum Likelihood Estimates Description Computes a confidence interval for one or more parameters in a unvariateML object. Webconfint is a generic function. The default method assumes normality, and needs suitable coef and vcov methods to be available. The default method can be called directly for comparison with other methods. For objects of class "lm" the direct formulae based on t t values are used.
