We investigate a newsvendor problem where a decision-maker observes a z-dimensional vector of covariates, and wants to learn how much stock to order given a sample of size n of censored demand data to minimize costs. Demand is censored when insufficient stock is available to meet it, and past stocking quantities are kn...

We propose a general goodness-of-fit framework for distributions on separable metric spaces. Under suitable identifiability conditions, probability distributions are characterized by distance profiles, which motivates their use in goodness-of-fit testing, for simple and composite null hypotheses. For composite null hyp...

In survival analysis, the time-to-event variable T is frequently subject to right censoring. Individuals may withdraw from the study for various reasons, or may not experience the event of interest before the end of follow-up. In this paper, we distinguish between two types of censoring: a potentially dependent censori...
