Nonlinear split-plot design modeling and analysis of rice varieties yield

open access: yesScientific African, 2023
In this research, a class of nonlinear split plot design models where the mean function of the split-plot model is not linearizable is presented. This was done by fitting intrinsically nonlinear split-plot design (INSPD) models using the Chapman-Richards

Assessing the Performance of Hierarchical Forecasting Methods on the Retail Sector

open access: yesEntropy, 2019
Retailers need demand forecasts at different levels of aggregation in order to support a variety of decisions along the supply chain. To ensure aligned decision-making across the hierarchy, it is essential that forecasts at the most disaggregated level ...

Summertime response of ozone and fine particulate matter to mixing layer meteorology over the North China Plain [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Measurements of surface ozone (O3), PM2.5 and its major secondary components (SO42-, NO3-, NH4+, and organic carbon (OC)), mixing layer height (MLH), and other meteorological parameters were made in the North China Plain (NCP) during the warm season ...

Analysis of Fluid Velocity inside an Agricultural Sprayer Using Generalized Linear Mixed Models

open access: yesApplied Sciences, 2020
The fluid velocity inside the tank of agricultural sprayers is an indicator of the quality of the mixture. This study aims to formulate the best generalized linear mixed model to infer the fluid velocity inside a tank under specific operational ...

A Novel Approach for Gaussian Mixture Model Clustering Based on Soft Computing Method

open access: yesIEEE Access, 2021
Determining the number of clusters in a data set is a significant and difficult problem in cluster analysis. In this study, a new model-based clustering approach is proposed for the estimation of the number of clusters. In the proposed method, the number

On the Use of Information Criteria for Model Selection in Phylogenetics.

open access: yesMolecular biology and evolution, 2020
The information criteria AIC, AICc and BIC are widely used for model selection in phylogenetics, however their theoretical justification and performance have not been carefully examined in this setting.

Dynamic Changes, Spatiotemporal Differences, and Ecological Effects of Impervious Surfaces in the Yellow River Basin, 1986–2020

open access: yesRemote Sensing, 2023
Impervious surfaces (IS) are one of the most important components of the earth’s surface, and understanding how IS have expanded is vital. However, few studies on IS or urbanization have focused on the cradle of the Chinese nation—the Yellow River Basin (
