Oftentimes, application of regression models to analyse cereals data is limited to estimating and predicting crop production or yield. The general approach has been to fit the model without much consideration of the ...
Factors affecting the health status of the people of Lesotho.
Lesotho, like any other country of the world, is faced with the task of improving the
Linear model diagnostics and measurement error
The general linear model, the weighted linear model, and the generalized linear model are presented in detail. Diagnostic tools for the linear models are considered. In general the standard analysis for linear models does ...
A review of methods for modelling both Gaussian and Non-Gaussian longitudinal data with application.
The study of longitudinal data plays an integral role in medicine, epidemiology, social science, biomedical and health sciences research where repeated measurements are obtained over time for each individual. Generally, ...
Analysis of longitudinal binary data : an application to a disease process.
The analysis of longitudinal binary data can be undertaken using any of the three families of models namely, marginal, random effects and conditional models. Each family of models has its own respective merits and demerits. ...
