生命历程分析中的序贯预测模型评估AI 解读

We extend the prequential approach introduced by A. P. Dawid to continuous time marked pint processes. A prequential forecasting system is expressed by means of the stochastic intensities of the point process. The exact independence and 1-exponentiality of the derived compensators are used to assess the predictive performance of the model and the inferential procedure. Some key words : Bayesian inference; Goodness of fit; Marked pint process; Markov chain Monte Carlo;…

随机序约束下生存概率的贝叶斯推断AI 解读

In the statistical analysis of survival data arising from two populations, it often happens that the analyst knows, a priori, that the life lengths in one population are stochastically shorter than those in the other. Nevertheless, survival probability estimates, if determined separately from the corresponding samples, may not be consistent with this prior assumption, because of inherent statistical variability in the observations. This problem has been considered in a…
