Value

llogis_aft_density, llogis_aft_hazard, and llogis_aft_survival return the density, hazard, and survival of the specified survival distribution. The llogis_aft_log_density, llogis_aft_log_hazard, llogis_aft_log_survival return log of the corresponding qualities. llogis_aft_mean and llogis_aft_sd return the mean and standard deviation of the specified survival distribution. llogis_aft_r, llogis_aft_q, and llogis_aft_p return a random generation, quantiles, and cumulative probabilities of the specified survival distribution.
