The duration of trade revisited: Continuous-time versus discrete-time hazards
W Hess, M Persson - Empirical Economics, 2012 - Springer
The recent literature on the duration of trade has predominantly analyzed the determinants
of trade flow durations using Cox proportional hazards models. The purpose of this article is …

riskRegression: predicting the risk of an event using Cox regression models
In the presence of competing risks a prediction of the time-dynamic absolute risk of an event
can be based on cause-specific Cox regression models for the event and the competing …

Expectation maximization algorithm for one shot device accelerated life testing with Weibull lifetimes, and variable parameters over stress
In reliability analysis, accelerated life-tests are commonly used for inducing more failures,
thus obtaining more lifetime information in a relatively short period of time. In this paper, we …

Objective Bayesian survival analysis using shape mixtures of log-normal distributions
Survival models such as the Weibull or log-normal lead to inference that is not robust to the
presence of outliers. They also assume that all heterogeneity between individuals can be …
