Description: Different approaches to censored or truncated regression
        with conditional heteroscedasticity are provided. First,
        continuous distributions can be used for the (right and/or left
        censored or truncated) response with separate linear predictors
        for the mean and variance. Second, cumulative link models for
        ordinal data (obtained by interval-censoring continuous data)
        can be employed for heteroscedastic extended logistic
        regression (HXLR). In the latter type of models, the intercepts
        depend on the thresholds that define the intervals.
        Infrastructure for working with censored or truncated normal,
        logistic, and Student-t distributions, i.e., d/p/q/r functions
        and distributions3 objects.
