The Weibull model also has a proportional hazards interpretation.
The resemblance to the Cox model allows estimation of a hazard ratio, with the usual proportional hazards interpretation.
Despite being similar in nature, the latter formulation allows one to set both a lower and an upper bound on the progressivity index which have natural interpretations: proportional taxation and maximum redistribution in that net-of-tax incomes are equalized across taxpayers, respectively.
As illustrated in the example proportional differences greatly improve the interpretation of the results compared to absolute differences.
In view of the difficulties with the interpretation of the proportional odds ratio, which is greater than the corresponding rate ratio, we added an additional analysis related to the ratio of number of events between treatment arms.
Although labor and cost have decreased with the advent of novel technologies, the problem of variant interpretation has increased proportional to the range and sensitivity of the screening methods.
Results and interpretation from the Cox proportional hazards models did not differ from those obtained using Gompertz and Weibull parametric survival models.
Thus, our interpretations are based on proportional rather than absolute differences in mean stress values and distributions.
We instead accord the Department's interpretation a measure of deference proportional to the " 'thoroughness evident in its consideration, the validity of its reasoning, its consistency with earlier and later pronouncements, and all those factors which give it power to persuade.' " United States v. Mead Corp., 533 U. S. 218, 228 (2001) (quoting Skidmore v. Swift & Co., 323 U. S. 134, 140 (1944) ).
When the assumption of proportional baseline cause-specific hazards is satisfied, interpretation of the estimates from the unstratified Lunn and McNeil model is straightforward and allows assessment of the relative clinical importance of different event types.
