Numerical methods for weather derivatives pricing by Nhangumbe, Clarinda

“…Mispricing these contracts poses a significant risk due the nature of weather variable. On rainfall derivatives pricing, the rainfall process is considered to be a stochastic, consisting of two random variables: one representing frequency, which is a two state Markov Chain, and the other representing the rainfall amount. …”

Environmental factors influencing the distribution of bats (Chiroptera) in South Africa by Salata, Hassan Aburaida Babiker

“…However, the results of this study should be interpreted cautiously. The majority of the environmental variables employed in this study to model the distribution of bats, were correlated to some degree, which could affect the contribution of an individual environmental variable to the performance of a model. …”

Modelling Multivariate Nonlinear Vaccine Induced Immune Responses by Lapham, Brendon M

“…In addition, the Tweedie multivariate generalised linear mixed effect and latent variable models have several advantages over the other models we consider and are also capable of interpretation; importantly, we are able to draw clinical conclusions about which novel TB vaccine candidates appear to be the most promising.…”

Comparison of growth curve models for assessing height in a South African birth cohort by Niehaus, Jacqui

“…The random forest model appeared to perform similarly to the logistic regression model in terms of predictive power and variable interpretation. This dissertation contributes in investigating the possibility of using machine learning techniques to identify probable correlates of childhood malnutrition.…”
