ABSRACTPrimarily, the project has focused on finding out the Online Buying trendsand behavior of Maasai Mara university consumers with an age range of 18- 25years. The proposed primary objective of the study was further divided intosecondary objectives with an aiming of finding detailed information on theresearch topic. Precisely, information regarding buyer’s buying frequency, averagespending, and famous product purchase was gathered. Since the objectives werequantifiable, a quantitative e...

Seasonal Responses Of Total Antioxidant Level In Cultivated Tea To Fertilizer

ABSTRACTThe research was conducted to find out whether applying fertilizer to tea at specific season of the year will affect the level of antioxidant. The main objective of the research was to determine the correlation between the level of antioxidant in tea and the season at which fertilizer was applied. Secondary data was obtained from James Finlay Kenya Limited with the authority of Applied Research Department. Trials of NPK fertilizer were conducted during the four seasons of the year: dr...

Estimation Of Variation About The Mean Using Geometric Measure

ABSTRACT A measure of dispersion is a statistical tool used to define the distribution of various datasets mainly from measures of central tendency. Some notable measures of dispersion from the mean are; average deviation, mean deviation, variance, and standard deviation. However, from previous studies, it has been established that the aforementioned measures are not absolutely perfect in estimating average variation from the mean. For instance, variance gives estimates which are of...

Influence Of Human Resource Management Practices On Growth Of Sacco Societies In South Rift Region

ABSTRACTHuman Resource Management (HRM) practices will continually attract the attention of researchers in pursuit of better ways to counter the emerging challenges that can undermine the growth of the organizations. The research will be carried out to examine the influence of human resource management practices on the growth of Savings and Credit cooperative societies (Sacco societies) in South Rift Region. The study will examine the relationship among the factor variables which are; selecti...

Determination Of Actuarial Costing On Non-Remitted Contribution For A Defined Contribution Scheme

ABSTRACTIncome accrued from Retirement Bene ts Fund is an exceptionally important component ofevery working individual's life cycle globally. The major sources of such income are: unfundedstate pensions; funded private pensions; mandatory schemes; and post-retirement work. Theurgency and importance has made many countries to give it considerable attention by enactingenabling laws and policies to safeguard it. In Kenya, steps have been made by establishing theNational Social Security Fund and ...

A Mathematical Model For The Optimal Control Of Trypanosomiasis In A Cattle Population.

AbstractTrypanosomiasis is a debilitating disease which is a major constraint to livestock productionin sub-Saharan Africa. It leads to loss of productivity in animals and without treatment it isfrequently fatal. The economic and social repercussions it causes in areas where it is endemic,makes its control a priority operation. In this study we formulate three models; a basic modelto understand the transmission dynamics of the trypanosomiasis in a cattle population, amodel with treatment to e...

Discriminant Analysis Of Factors That Have Led To Slow Decline Of Hiv/Aids Prevalence: Case Study Of Maseno

ABSTRACTHIV/AIDS epidemic has endangered the development of countries in this new century, presenting one of the greatest challenges of this generation and threatening human development. To accomplish an efficient response requires many researches to find long term solutions. Though its prevalence has declined in the past years, it is still very high in particular regions due to various factors. This research analysed major factors associated with HIV/AIDS prevalence in Maseno Community. If n...

Arima Model For Forecasting Of Monthly Rainfall And Temperature In The Lake Victoria Basin

AbstractEconomic activities in Lake Victoria Basin such as agriculture, sh-ing, mining and transportation depend's heavily on the climaticconditions of the Lake and its Basin. Global climatic change causedby Greenhouse Gas emission (GHG) has resulted in a disruptive anderratic weather pattern for these economic activities. This unpre-dictable weather variations is responsible for loss of life and destruc-tion of property. The primary cause of this negative impact is lackof a reliable informa...

Statistical Distributions And Modelling Of GPS-Telemetry Elephant Movement Data Including The E_Ect Of Covariates

AbstractIn this thesis, I investigate the application of various statistical methods towardsanalysing GPS tracking data collected using GPS collars placed on large mammalsin Kruger National Park, South Africa. Animal movement tracking is a rapidlyadvancing area of ecological research and large amount of data is being collected,with short sampling intervals between successive locations. A statistical challengeis to determine appropriate methods that capture most properties of the datais lackin...

Statistics Project Review Of Methods Of Estimating Parameters In Nonlinear Mixed-Effects (Nlme) Models

Abstract.This study is a critical review of theoretical issues that underline the linear mixed effects(LME) and nonlinear mixed effects (NLME) models. These two areas are revisited undermaximum likelihood and restricted maximum likelihood estimation frameworks. We alsoreview 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, keyamong these methods are the “pseudo-data” a...

SPATIAL ANALYSIS AND MAPPING OF INFANT MORTALITY IN KENYA ON THE BASIS OF DEMGRAPHIC AND HEALTH SURVEY DAT

AbstractThis study set out to examine and map the spatial variation of infant mortality in Kenya. We used data from Demographic and Health Survey (DHS) database to explore spatial variation. Generalized linear mixed inodel(GLMM) with Enumeration Areas (EA) specific random effects was used to assess the effects of geographical heterogeneity and other covariates. The model based Geostatistical methods were used to quantify the spatial variations of the observations using the variograms and fitt...

Hierarchical Logistic Regression Model For Multilevel Analysis : An Application On Use Of Contraceptives Among Women In Reproductive Age In Kenya

ABSTRACTContraception allows women and couples to have the number of childrenthey want, when they want them. This is everybody’s right according tothe United Nations Declaration of Human Rights. Use of Contraceptivealso reduces the need for abortion by preventing unwanted pregnancies.It therefore reduces cases of unsafe abortion,one of the leading causes ofmaternal death worldwide.According to Mohammed ,in 2012 an estimated464,000 induced abortions occurred in Kenya. This translates into an...

Primary Educationforms the basis of implementing Poverty Reduction Strategy by the governmentthrough the acquisition of basic literacy skills, which increases opportunities for employmentand ability to be self-reliant, hence the need to monitor the pupils generalprogress from the time of entry in class one to graduation after the expe...

Application Of Auto-Regression Integrated Moving Avaerage Model To Forecast Tea Prices At Mombasa Tea Auction Center In Kenya

ABSTRACTTea production is the mainstay of many people in Kenya. The contribution of tea sectorto the Kenyan economy is enormous as it accounts for about 4% of Gross DomesticProduct (GDP). Favourable product prices act as a trigger for any commercial activityover time and also suggest sustainability of the activity. Tea is a very significant cropin Kenya and it is one of the major agricultural exports of the country. However, theindustry has experienced many challenges such as stiff competitio...

Forecasting Foreign Exchange Rates In Kenya Using Time Series: A Case Of Usd/Kes Exchange Rates

ABSTRACTIn October 1993, Kenya adopted a floating exchange rate system where the exchangerates are determined by forces of demand and supply for the local currency. Exchange rateforecasts are necessary to evaluate the foreign denominated cash flows involved in internationaltransactions. Therefore exchange rate forecasting is important to evaluate the benefitsand risks attached to the international business environment. This study thereforesought to fit a Seasonal Autoregressive Intergrated Mo...
