Abstract This study is a critical review of theoreticalissues that underline the linear mixed effects (LME) and nonlinear mixed effects (NLME) models. These two areas are revisited under maximum likelihood and restricted maximumlikelihood estimation frameworks. We also review methods of estimating parameters in both linear and nonlinear mixed effects models. In the case of LME, we consider different ways of developing the likelihood estimators, key among these methods are the “pseudo-data�...
ABSTRACT Biologically, every living thing has a general property. One of these properties is movement. As a result of this movement, some hazard can occur. One of these hazards is accident. Generally, in Nigeria, the major mode of movement is by road. Road accident has become a major threat to lives of citizens of the country especially during the festive period. The increasing magnitude of fatal road traffic accident globally has been attributed to population explosion and increased leve...
ABSTRACTAIDS is an acronym for acquired immune deficiency syndrome it cause a destruction of the immune system. It is the most advance stage of HIV viruses (Human Immune deficiency syndrome Virus). This research work is carried out to determine the relationship between male and female HIV patient using data collected from National Tuberclosis and Leprosy training centre Says Zaria. The model arrived in this research. It shows a linear trend model for the male patients Yt=2038 -55.4,364*t show...
ABSTRACT This work suggests an exact and systematic model identification approach which is entirely new and addresses most of the challenges of existing methods. We developed quadratic discriminant functions for various orders of autoregressive moving average (ARMA) models. An Algorithm that is to be used alongside our functions was also developed. In achieving this, three hundred sets of time series data were simulated for the development of our functions. Another twenty five sets of simul...
Abstract Several authors have developed statistical procedures for testing whether two models are similar. In this work, we not only present the notion of equivalence but also extend this to a measure of predictive ability of a time series following a stationary self-exciting threshold autoregressive (SETAR) process. A proposition and a lemma were used to join the structure of the predictability measure to the coefficients and sample autocorrelation of the SETAR process. Illustrative examples...
ABSTRACT This study was motivated by the fact the Uganda has one of the fastest population growth rates in the world accompanied by high unemployment rates thus the study aimed at investigating the relationship between population growth rates and youth unemployment in Uganda (1991 to 2014). The specific objectives of the study were; to find out the long run relationship between the population growth rate and youth unemployment rate in Uganda, to examine the causality between population growth...

ABSTRACT This report investigated Road Infrastructure and Economic Growth in Uganda 2000 .- 2018, the Study considered all national roads, that is, paved and unpaved roads however, district roads were excluded due to lack of data for the entire period of the study. The emphasis on national roads was both due to data availability and the multiplier effects associated with these roads towards economic growth. The objectives of the study were to: establish the causality between economic growth a...

ABSTRACT This study investigated the effect of food supply on household incomes. A discipline correlation design was applied in examining the effect of food supply and household income. A sample of 250 respondents selected, however, one of the limitations of alteration beyond the researcher’s control, only 70 questionnaires are retrieved. The findings indicated that the effect of food expenses on household incomes was so high due to the fact that people totally do not have food at all, so t...
