Generalizing the normality: a novel towards different estimation methods for skewed information
Diego C Nascimento, Pedro Luiz Ramos, David Elal-Olivero +2
Normality is the most often mathematical supposition used in data modeling. Nonetheless, even based on the law of large numbers (LLN), normality is a strong presumption given that…
Noniterative Likelihood-Derived Estimation through Auxiliary Estimating Equations
Pedro L. Ramos, Eduardo Ramos, Francisco A. Rodrigues +1
Closed-form estimators are useful when parametric models are repeatedly refitted but likelihood maximization is iterative. We study a likelihood-derived construction of auxiliary e…
Objective Bayesian Analysis for the Differential Entropy of the Gamma Distribution
Eduardo Ramos, Osafu A. Egbon, Pedro L. Ramos +2
The present paper introduces a fully objective Bayesian analysis to obtain the posterior distribution of an entropy measure. Notably, we consider the gamma distribution, which desc…
Sampling with censored data: a practical guide
Pedro L. Ramos, Daniel C. F. Guzman, Alex L. Mota +3
In this review, we present a simple guide for researchers to obtain pseudo-random samples with censored data. We focus our attention on the most common types of censored data, such…
Power laws in the Roman Empire: a survival analysis
Pedro L. Ramos, Luciano da F. Costa, Francisco Louzada +1
The Roman Empire shaped Western civilization, and many Roman principles are embodied in modern institutions. Although its political institutions proved both resilient and adaptable…
Incorporation of frailties into a non-proportional hazard regression model and its diagnostics for reliability modeling of downhole safety valves
Francisco Louzada, José A. Cuminato, Oscar M. H. Rodriguez +13
In this paper, our proposal consists of incorporating frailty into a statistical methodology for modeling time-to-event data, based on non-proportional hazards regression model. Sp…
