I know with the mlogit command, you can specify the 'relative risk ratio'. This point was made clear by (hernan, 2010) in commentary, which emphasised that the hazard ratio contrasts populations of treated and untreated. In survival analysis, the hazard ratio (hr) is the ratio of the hazard rates corresponding to the conditions described by two levels of an explanatory variable.
If we wanted information about the coecient, , we could use the nohr option general syntax.
Since the distribution of the log hazard ratio is nearly normal, the log transformation is applied. These are the hazard ratios using robust standard errors. •the hazard ratio is not computed at any one time point, but is computed from all the data in the survival curve. Used to reflect time survived to an event.
