Robust autoregressive modeling and its diagnostic analytics with a COVID-19 related application

Y Liu, J Wang, V Leiva, A Tapia, W Tan… - Journal of Applied …, 2024 - Taylor & Francis
Autoregressive models in time series are useful in various areas. In this article, we propose
a skew-t autoregressive model. We estimate its parameters using the expectation …

Bayesian analysis of censored linear regression models with scale mixtures of normal distributions

AM Garay, H Bolfarine, VH Lachos… - Journal of Applied …, 2015 - Taylor & Francis
As is the case of many studies, the data collected are limited and an exact value is recorded
only if it falls within an interval range. Hence, the responses can be either left, interval or …

Bayesian estimation and case influence diagnostics for the zero-inflated negative binomial regression model

AM Garay, VH Lachos, H Bolfarine - Journal of Applied Statistics, 2015 - Taylor & Francis
In recent years, there has been considerable interest in regression models based on zero-
inflated distributions. These models are commonly encountered in many disciplines, such as …

We present a proposal to deal with the non-normality issue in the context of regression
models with measurement errors when both the response and the explanatory variable are …

Multivariate measurement error models based on Student-t distribution under censored responses

LA Matos, LM Castro, CRB Cabral, VH Lachos - Statistics, 2018 - Taylor & Francis
