Comparing performance between log-binomial and robust Poisson regression models for estimating risk ratios under model misspecification

open access: yesBMC Medical Research Methodology, 2018
BackgroundLog-binomial and robust (modified) Poisson regression models are popular approaches to estimate risk ratios for binary response variables. Previous studies have shown that comparatively they produce similar point estimates and standard errors ...

Jackknifed Liu-type Estimator in Poisson Regression Model

open access: yes, 2020
The Liu estimator has consistently been demonstrated to be an attractive shrinkage method for reducing the effects of multicollinearity. The Poisson regression model is a well-known model in applications when the response variable consists of count data.

Boosting Poisson regression models with telematics car driving data

open access: yesMachine-mediated learning, 2020
With the emergence of telematics car driving data, insurance companies have started to boost classical actuarial regression models for claim frequency prediction with telematics car driving information.

Poisson regression analysis of ungrouped data [PDF]

open access: yesOccupational and Environmental Medicine, 2005
Background:Poisson regression is routinely used for analysis of epidemiological data from studies of large occupational cohorts. It is typically implemented as a grouped method of data analysis in which all exposure and covariate information is categorised and person-time and events are tabulated.Aims:To describe an alternative approach to Poisson ...

Poisson regression charts for the monitoring of surveillance time series [PDF]

open access: yes, 2006
This paper presents a Poisson control chart for monitoring time series of counts typically arising in the surveillance of infectious diseases. The in-control mean is assumed to be time-varying and linear on the log-scale with intercept and seasonal ...

PENERAPAN REGRESI BINOMIAL NEGATIF UNTUK MENGATASI OVERDISPERSI PADA REGRESI POISSON

open access: yesE-Jurnal Matematika, 2013
Poisson regression was used to analyze the count data which Poisson distributed. Poisson regression analysis requires state equidispersion, in which the mean value of the response variable is equal to the value of the variance.

EM Estimation for Zero- and k-Inflated Poisson Regression Model

open access: yesComputation, 2021
Count data with excessive zeros are ubiquitous in healthcare, medical, and scientific studies. There are numerous articles that show how to fit Poisson and other models which account for the excessive zeros. However, in many situations, besides zero, the

Overdispersion study of poisson and zero-inflated poisson regression for some characteristics of the data on lamda, n, p

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2016
Poisson distribution is one of discrete distribution that is often used in modeling of rare events. The data obtained in form of counts with non-negative integers. One of analysis that is used in modeling count data is Poisson regression.

Improved log-Gaussian approximation for over-dispersed Poisson regression: Application to spatial analysis of COVID-19.

open access: yesPLoS ONE, 2022
In the era of open data, Poisson and other count regression models are increasingly important. Still, conventional Poisson regression has remaining issues in terms of identifiability and computational efficiency.
