The method thus estimates a baseline hazardfunction which is modified by the coefficient estimates for the various independent variables. Survival curves were generated, and gains in life expectancy were estimated, from the baseline cumulative hazardfunction and prognostic index. Semi-parametric models require no assumption on the functional form of the baseline hazardfunction, so they are more flexible than parametric models. To associate covariate effects and hazardfunction, proportional hazard models are the most popular. With follow-up limited to only a few years, estimates of survival gains have been truncated, reflecting the estimated hazardfunction. We must collect at least one more data point than there are unknown parameters in the individual growth model or in the baseline hazardfunction. Factors associated with death after repair were sought by parametric modeling of the time-varying hazardfunction. The knots for the splines were determined from inspection of the hazardfunction for males and females combined. If the event is equally likely to occur at any given age, the hazardfunction will be flat. Survival gains were estimated for 3.3 years following treatment, since this was the time span over which the underlying hazardfunction was calculable. Does the hazardfunction peak, and if so, when? The advantages associated with additional waves of data collection depend, in part, upon the shape of the growth trajectory or the baseline hazardfunction. These more complex analytic goals are achieved by postulating and fitting statistical models of the hazardfunction and by conducting tests on the parameters of these models. Multjvariate analysis in hazardfunction domain indicates early repair as a negativeriskfactor for death (p=0.038). However, the biological applicability of this model may be limited by the fact that the hazard function is monotonic, i.e. either decreasing of increasing.

Fitted hazard functions describing age at first onset of depression by gender and whether the respondent's parents had divorced. Examination of empirical growth trajectories and sample hazard functions computed separately by values of each predictor can often suggest reasonable places to begin. The model assumes that the ratio of the hazard functions for two observations with different values for the independent variables does not depend on time.
