A multiple matrix model to study the population dynamics of R. appendiculatus in Zimbabwe

Autor: Mwambi, H.G. Odhiambo, J.W. Duchateau, L.

The classical Leslie matrix methodology is extended to describe the life cycle of the brown ear tick (R. appendiculatus), incorporating both within and between stage transitions of the population. We use data from the highveld of Zimbabwe Reported in Short et al. (1989a,b). The model incorporates...

A spatially predictive logistic regression model for occurrence of theileriosis outbreaks in Zimbabwe

Autor: Pfeiffer, Dirk U. Duchateau, L. Kruska, R.L. Ushewokunze-Obatolu, U. Perry, Brian D.

Multivariate logistic regression models are mostly used to identify risk factors associated withthe occurrence of particular disease processes. Logistic regression models have also been used as tools for veterinary diagnosis by providing the probability of a particular disease in an individual an...

Comparing the mixed model and the fixed effects model: Do the advantages justify the costs?

Autor: Duchateau, L.

Mixed models have important advantages as compared to fixed effects models. Complex data structures can be described in a natural way in mixed models. The analysis of unbalanced data is a straightforward extension of the analysis of balanced data in the mixed model framework. Furthermore, the app...
