Contribution of Innovations to Enterprise Growth of Small and Medium Electrical Machinery Enterprises in Nairobi County, Kenya
(Researchjournali’s Journal of Entrepreneurship, 2014) -
The moderating influence of employee engagement on the relationship between labour productivity and performance based reward
(nternational Journal of Advanced Research in Management and social Sciences, 2014)The performance and productivity of each individual in an organization leads to the prosperity of the organization and a nation as a whole. Labour productivity is therefore very important since it indicates the extent to ... -
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... -
Effects of outliers on Estimation of Finite Population Totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of outliers on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate of finite ... -
Innovation Activity and Firm Growth Across Key Sectors of the Kenyan Economy
(JKUAT Press Ltd, 2013)More than ever there is a global concern to entrench financial deepening and access to previously ignored areas considered economically unviable where majority of the micro and small enterprises operate through provision ... -
Parametric Modeling of Probability of Bank Loan Default in Kenya
(JAGST, 2012)Commercial banks in Kenya are the key players not only in the financial market but also in spurring the economic growth that has been witnessed in the country in the recent past. Besides Safaricom and East Africa Breweries, ... -
Multivariate ratio estimator of the population total under stratified random sampling
(Scientific Research Publishing, 2012)Olkin [1] proposed a ratio estimator considering p auxiliary variables under simple random sampling. As is expected, Simple Random Sampling comes with relatively low levels of precision especially with regard to the fact ... -
The Strategic Kenyan Business Selection Tool for MSMEs
(International Journal of Business and Management Tomorrow, 2012) -
Business Selection using Multi-Criteria Decision Analysis
(International Journal of Business and Commerce, 2012)One of the major challenges facing an entrepreneur in business prioritization entails coming-up with a reliable model that will rank the available opportunities (what type of business to be invested?). Usually, investors ... -
Deriving Some Estimators of Panel Data Regression Models with Individual Effects
(International Journal of Science and Research, 2012) -
Prediction of the likelihood of Households Food Security in the Lake Victoria Region of Kenya
(Pakistan Journal of Statistics and Operation Research, 2011)This paper considers the modeling and prediction of households food security status using a sample of households in the Lake Victoria region of Kenya. A priori expected food security factors and their measurements are ... -
Modelling the volatility of exchange rates in the Kenyan market
(Academic Journals, 2010)This paper considers the application of the generalized autoregressive conditional heteroscedasticity process in the estimation of volatility in the Kenyan exchange rates. A quasi-maximum likelihood estimation procedure ... -
Nonparametric model assisted model calibrated estimation in two stage survey sampling
(JKUAT Press Ltd, 2007) -
Non-response weighting adjustment approach in survey sampling
(JKUAT Press Ltd, 2006)Non-response problem is an issue of great concern to all the researchers because it pervades almost all survey research. This ultimately creates potential for bias. The higher the non-response rate the greater the bias if ... -
Seasonal time series data imputation: comparison between feed forward neural networks and parametric approaches
(JKUAT Press Ltd, 2005)Missing data in a time series may be an obstacle that may prevents further analysis of the available series either for control, explanations or forecasting. This paper addresses the problem of "‘filling in"' missing data ... -
Seasonal time series forecasting: A comparative study of ARIMA and ANN models
(African Journal of Science and Technology (AJST), 2004)This paper addresses the concerns of Faraway and Chatfield (1998) who questioned the forecasting ability of Artificial Neural Networks (ANN). In particular the paper compares the performance of Artificial Neural Networks ... -
Robust estimation of variance in the presence of nearest neighbour imputation
(African Network of Scientific and Technical Institutions (ANSTI), 2003)The problem of estimating the variance of an estimator of the population total when missing values have been filled using a Nearest Neighbour (NN) imputation method is considered. The estimator is developed assuming a more ... -
Outlier Robustness of the Estimators of Variance of the Ratio Estimator
(Jomo Kenyatta University of Agriculture and Technology (JKUAT), 2002) -
Robust estimation of the error variance of the ratio estimator
