A non-default fraction bivariate regression model for credit scoring: An applic...

Made available in DSpace on 2022-04-28T19:07:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-04-02; In this article, we propose a lifetime model for bivariate survival data with a non-default rate. Our approach enables different underlying activation mechanisms that lead to the event of interest. A number of competing causes which may be responsible for the occurrence of the event of interest are assu...

A new distribution for service model with state dependent service rate

Made available in DSpace on 2022-04-28T18:59:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-01-01; In this paper, we introduced a new distribution for the minimum service time in the system with a superserver, the Minimum-Conway-Maxwell-Poisson- exponential distribution (or MINCOMPE distribution). The service was attached to the arrival. Owing this fact, the service finishes when a customer arrives. ...

Objective Bayesian inference for the Capability index of the Weibull distributi...

Made available in DSpace on 2022-04-28T19:50:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-05-01; The Weibull distribution plays an important role in reliability and quality control monitoring. This model has been widely used to describe the process capability index (PCI) when data do not follow a normal distribution. In this scenario, the current studies focus on estimating the parameters using cla...

A New Class of Cure Rate Survival Models: Properties, Inference and Applications

Made available in DSpace on 2021-06-25T12:17:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; We propose a new class of survival models for time-to-event data with a cure fraction. This new model is an extension of the promotion time cure rate model. Furthermore, we extend the model to the regression model to evaluate the effect of covariates in the cure fraction. An expectation-maximization alg...

Statistical modeling of hospital admissions for pneumonia in Campo Grande

Justification and Objectives: Brazil lacks consistent epidemiological data on the respiratory morbidity of children and older adults, which makes it difficult to plan and execute effective preventive and health promotion actions. The objective of this study was to analyze the adjustments of distributions (Weibull, Normal, Gamma, Logistic) of historical series of hospitalizations for respiratory diseases (total ...
