The Conway-Maxwell-Poisson-generalized gamma regression model with long-term survivors
(Taylor & Francis Ltd, 2011-01-01)
In this paper, we proposed a flexible cure rate survival model by assuming the number of competing causes of the event of interest following the Conway-Maxwell distribution and the time for the event to follow the generalized ...
Zero-Truncated Poisson Exponentiated Gamma Distribution: Application and Estimation Methods
(Springer, 2019-12-01)
We define a new two-parameter lifetime model called the zero-truncated Poisson exponentiated gamma distribution. The hazard function of the new distribution has monotonic and non-monotonic shapes, which allows to fit more ...

The Conway-Maxwell-Poisson-generalized gamma regression model with long-term survivors

A new bayesian Poisson denoising algorithm based on nonlocal means and stochastic distances
(2022-02-01)
Poisson noise is the main cause of degradation of many imaging modalities. However, many of the proposed methods for reducing noise in images lack a formal approach. Our work develops a new, general, formal and computationally ...
On estimation and influence measures for the Negative Binomial regression model based on Q-function
(TAYLOR & FRANCIS INC, 2021)
In this paper the influence measures for the Negative Binomial regression model are presented. Based on the conditional expectation of the complete-data log-likelihood function we derive some influence measures, such as ...
Beta-binomial/gamma-poisson regression models for repeated counts with random parameters
(Brazilian Statistical Association, 2011-07)
Beta-binomial/Poisson models have been used by many authors to model multivariate count data. Lora and Singer [Stat. Med. 27 (2008) 3366-3381] extended such models to accommodate repeated multivariate count data with ...
A Poisson mixed model with nonnormal random effect distribution
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we propose a random intercept Poisson model in which the random effect is assumed to follow a generalized log-gamma (GLG) distribution. This random effect accommodates (or captures) the overdispersion in the ...
Resistant estimators in Poisson and Gamma models with missing responses and an application to outlier detection
(Elsevier Inc, 2013-02)
When dealing with situations in which the responses are discrete or show some type of asymmetry, the linear model is not appropriate to establish the relation between the responses and the covariates. Generalized linear ...
