exp_aft_density, exp_aft_hazard, and
exp_aft_survival return the density, hazard, and survival
of the specified survival distribution. The exp_aft_log_density,
exp_aft_log_hazard, exp_aft_log_survival return log of
the corresponding qualities. exp_aft_mean and exp_aft_sd
return the mean and standard deviation of the specified survival distribution.
exp_aft_r, exp_aft_q, and exp_aft_p return a random
generation, quantiles, and cumulative probabilities of the specified
survival distribution.
