How to define deviance residuals in multinomial regression.
2015
This work is devoted to the study of diagnostic tools for categorical data models with an emphasis on the presence of continuous covariates. In particular, the aim is to define a new class of residuals from the parametric multinomial family of models and to study their asymptotics properties. In logistic regression (as in generalized linear models), there are a few different kinds of residuals; we propose a generalization of deviance residuals as defined in logistic regression to the multinomial case and propose their use in order to identify inadequacies in a multinomial model.
Evaluation of Nigeria Universities Websites Quality : A Comparative Analysis
2018
The use and continuous use of the website in the developed countries universities are predominant, and the developing countries universities are heightening their effort in the aspect of education technology. The reason why one university website is better than the other concerning quality and accessibility is the focus of this study and this prompt evaluation of 141 Universities in Nigeria across the Federal, State, and the Private ownership. We opted for a hybrid approach to cover the gap in the previous studies. WebQual and SITEQUAL as a framework is adopted based on the web analytical tools. The study contributes theoretically by combining two website quality theories to explain the inh…
