WebOct 8, 2024 · For poisson or binomial GLMM, we can use the confint function to calculate the confidence interval. But the default setting (method = "profile) is not working for gamma GLMM. confint(fit) Computing profile confidence intervals ... WebOct 30, 2024 · The function conf_intervals calculates (profile, if necessary) likelihood-based confidence intervals for individual parameters, and also provides symmetric intervals based on a normal approximation to the sampling distribution of the estimator. chandwich also has a confint S3 method, which produces only the likelihood-based intervals.
