We propose a hazard model for entry into marriage, based on bell-shaped function to the dependence age. demonstrate near-aliasing in an extension that estimates support of and mitigate this via re-parameterization. Our proposed parameterizes maximum corresponding age, thereby facilitating more general models where these features depend covariates. For data women's marriages from Living Ireland ...

The generalization performance of a risk prediction model can be evaluated by its calibration, which measures the agreement between predicted and observed outcomes on external validation data. Here, we propose methods for assessing calibration discrete time-to-event models in presence competing risks. Specifically, consider class subdistribution hazard models, directly relate cumulative inciden...

The forecasting demand for new technology for which few historical data observations are available is difficult but essential to sustainable development. The current study suggests an alternative forecasting methodology based on a hazard rate model using stated and revealed preferences of consumers. In estimating the hazard rate, information is initially derived through conjoint analysis based ...

Cox regression model serves as a statistical method for analyzing the survival data, which requires some options such as hazard proportionality. In recent decades, artificial neural network model has been increasingly applied to predict survival data. This research was conducted to compare Cox regression and artificial neural network models in prediction of kidney transplant survival. The prese...

Air Products and Chemicals, Inc., to support compliance with regulatory requirements for communicating health and safety information in the shipping and handling of chemical products. This article concentrates on one of the knowledge bases in this system: the case-based reasoner. The casebased reasoner addresses the issue of how proper communication of public health and safety information can b...

In a principal–agent framework, principals can mitigate moral hazard problems not only through extrinsic incentives such as monitoring, but also through agents’ intrinsic trustworthiness. Their relative usage, however, changes over time and varies across societies. This paper attempts to explain this phenomenon by endogenizing agent trustworthiness as a response to potential returns. It …nds th...
