WebbExcept for the heaviest ties in the smallest sample, confidence interval coverage for all three estimators fell in the range of 94-96%. However, the tail probabilities were asymmetric with the Breslow and Kalbfleisch-Prentice formulas; using the Efron approximation, they were closer to the nominal 2.5%.

WebbHandling of ties glmnet handles ties in survival time with the Breslow approximation. This is different from survival package’s coxph function, whose default tie-handling method is … WebbNotes. The Breslow estimator is a nonparametric estimator of the survival function of a time-to-event distribution defined as the exponential of the negative of the Nelson-Aalen cumulative hazard function estimator A ^ ( t): S ^ ( t) = exp ( − A ^ ( t)). This estimator was introduced in a discussion [1] following [2]. WebbI'm analyzing the results of some simulation work using a Cox proportional hazard model, and I have what I perceive are a great many ties in the data, representing when a particular individual in the simulation was infected. For example, one of the (many) runs of this model: Time, Freq 1, 8 2, 9 3, 5 4, 5 5, 6 6, 4 7, 1 8, 6 9, 4 10, 1 11, 3 12, 2 jonathan antoine tour schedule
