Modelling of tea mosquito bug (Helopeltis theivora) incidence on neem tree: A zero inflated count data analysis

نویسندگان

چکیده

Neem (Azadirachta indica) is an evergreen tree belonging to the Meliaceae family and highly infected by seasonal pest called Helopeltis theivora, tea mosquito bug. The study monitors infection between May 2019 April 2021 direct counting method. Weekly counts of insect population were found be correlated with weather parameters viz., maximum temperature (Tmax.), minimum (Tmin), relative humidity [morning (07.22hrs) afternoon (14.22hrs) (RH)], rainfall (mm/day) wind speed (km/h). Zero inflated count data techniques opted for modelling dynamics bug as was featured excess zeroes heteroscedasticity nature. Poisson, Negative Binomial (NB), zero-inflated (ZINB) Hurdle (NBH) models fitted collected compared. results different show that negative binomial hurdle model a good fit given data, followed model. covariates, which influencing infestation on neem tree.

Semiparametric analysis of zero-inflated count data.

Medical and public health research often involve the analysis of count data that exhibit a substantially large proportion of zeros, such as the number of heart attacks and the number of days of missed primary activities in a given period. A zero-inflated Poisson regression model, which hypothesizes a two-point heterogeneity in the population characterized by a binary random effect, is generally...

Mediation analysis for count and zero-inflated count data.

Different conventional and causal approaches have been proposed for mediation analysis to better understand the mechanism of a treatment. Count and zero-inflated count data occur in biomedicine, economics, and social sciences. This paper considers mediation analysis for count and zero-inflated count data under the potential outcome framework with nonlinear models. When there are post-treatment ...

Semiparametric analysis of longitudinal zero-inflated count data

Background: The instrumental activities of daily living (IADLs) are important index of physical functioning in older adult studies. These count outcomes with a large proportion of zeros are often collected in longitudinal studies. Data were from the Hispanic Established Population for Epidemiological Study of the Elderly (HEPESE), a four wave (seven years) longitudinal study of community-dwelli...

Modeling zero-inflated count data with glmmTMB

Ecological phenomena are often measured in the form of count data. These data can be analyzed using generalized linear mixed models (GLMMs) when observations are correlated in ways that require random effects. However, count data are often zero-inflated, containing more zeros than would be expected from the standard error distributions used in GLMMs, e.g., parasite counts may be exactly zero fo...

On Baseline Conditions for Zero-Inflated Longitudinal Count Data

We describe a mixed-effects hurdle model for zero-inflated longitudinal count data, where a baseline variable is included in the model specification. Association between the count data process and the endogenous baseline variable is modeled through a latent structure, assumed to be dependent across equations. We show how model parameters can be estimated in a finite mixture context, allowing fo...
