For this reason, we created an interaction between the covariate measuring the percentage of frontloaded primaries with the party of the candidate. The candidate party variable is a binary, denoted 1 if the candidate is a Republican and 0 if the candidate is a Democrat. 56 is the mean for Democrats.

The defining feature of the Weibull parameterization of the baseline hazard is that it is characterized as monotonic. The baseline hazard given by the Weibull can be monotonically increasing, monotonically decreasing or flat with respect to time. Because a flat hazard can be produced by the Weibull, it turns out that the exponential distribution is simply a special case of the Weibull. It is important to point out that just as the assumption of a flat hazard seems unrealistic for many applied social science questions, so too does the assumption of ever-increasing or ever-decreasing hazard rates.

Consequently, it becomes clear how event history methods can account for both censored and uncensored observations. Moreover, the event history approach is clearly preferable to the alternative “solution” of omitting censored cases from the data set. By deleting censored cases from the analysis, we may induce a form of case selection bias into the results. If censored cases are systematically different from uncensored cases, then simply deleting the latter cases will produce a nonrepresentative “sample” and render coefficient estimates biased due to the case selection process.
