Selection of Peach Varieties and the Role of Quality Attributes

open access: yesJournal of Agricultural and Resource Economics, 2003
Timely adoption of new varieties is critical to profitable peach production, and peach quality is a primary factor driving adoption. An adoption model for peach varieties is estimated, incorporating grower evaluations of peach quality.

The Poisson-generalised Lindley distribution and its applications [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
The Poisson distribution plays important role in count data analysis. However, the Poisson distribution cannot model some data with over-dispersion because of its property, equi-dispersion.

Negative Binomial Mixed Models for Analyzing Longitudinal Microbiome Data

open access: yesFrontiers in Microbiology, 2018
The metagenomics sequencing data provide valuable resources for investigating the associations between the microbiome and host environmental/clinical factors and the dynamic changes of microbial abundance over time.

A Transition Model for Analysis of Zero-Inflated Longitudinal Count Data Using Generalized Poisson Regression Model

open access: yesRevstat Statistical Journal, 2020
In most of the longitudinal studies, involving count responses, excess zeros are common in practice. Usually, the current response measurement in a longitudinal sequence is a function of previous outcomes.

POISSON REGRESSION MODELLING OF AUTOMOBILE INSURANCE USING R

open access: yesBarekeng, 2022
Automobile insurance benefits are protecting the vehicle and minimizing customer losses. Insurance companies must provide funds to pay customer claims if a claim occurs. Insurance claims can be modelled by Poisson regression.

Partitioning variation in multilevel models for count data.

open access: yesPsychological methods, 2020
A first step when fitting multilevel models to continuous responses is to explore the degree of clustering in the data. Researchers fit variance-component models and then report the proportion of variation in the response that is due to systematic ...

The zero inflated negative binomial – Crack distribution: some properties and parameter estimation [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
The zero inflated negative binomial-Crack (ZINB-CR) distribution is a mixture of Bernoulli distribution and negative binomial-Crack (NB-CR) distribution, which is an alternative distribution for the excessive zero counts and overdispersion.
