confint() methods for the whole family, one interval rule per inference type: bootstrap percentile intervals for cpb() (coefficients; the dispersion parameter gets its profile-likelihood interval, first-order or calibrated by calibrate_alpha()) and gec() (coefficients and delta); normal-approximation intervals from the bootstrap standard errors for the fixed-effects fits (cpb_fe(), gec_fe()) and the zero-inflated mixtures (zi_cpb(), zi_gec()); Wald intervals from the analytic covariance for count_reg() and zi_count() (the dispersion parameter's interval is mapped from its estimation scale to the natural scale); and, for the hurdles, the participation model's Wald intervals (prefixed participation:) stacked over the intensity model's intervals (prefixed intensity:); the zero-inflated classes prefix count: and zero:. The same names label vcov(), tidy(), and the texreg tables. A fit without inference errors informatively.
