    Abstract: Schools are considered as the backbone for long-term economic progress. No country can develop without increasing their education level. Despite the fact that the Portuguese population shows a brilliant development in their educational level from last decade, but still Portugal lies on the tail surrender of Europe in statistics because of excessive...

    Abstract: The impacts of extremely high temperatures on plants, human beings and animals’ health have been studied in several parts of the world. However, extreme events are uncommon and have only attracted attention recently. In this study, extreme temperature behavior was modelled through the application of extreme value theory using maximum monthly temper... Show More

    Abstract: The standard Poisson distribution is widely used as a mechanism for regression modeling of count data outcomes. However, the suitability of this modeling technique is only limited to equi-dispersed count data outcomes. This is due to the fact that this modeling technique does not take into account the problems associated with over dispersion and ex... Show More

    Abstract: The transmission rates of HIV from a HIV-positive mother to her child during pregnancy, delivery or breastfeeding remains of much concern. Various governments and non-governmental organizations have aimed at coming up with policies aimed at minimizing the transmissions. For this to be achievable, there is a need for sound statistical procedures in ... Show More

    Abstract: In modelling count data, the use of least square regression models suffers several methodological limitations and statistical properties in instances of discrete, non-negative integer count of a dependent variable. Unlike the classical regression model, count data models are non-linear with many properties of the response variable relating to discr... Show More
