Master's thesis is focused on implementing modern statistical methods for fitting propability distribution using kernel estimates with regard to the possibilities of their implementation on the PC and the application of specic data sets. Master's thesis is a part of project from MSMT of the Czech Republic no. 1M06047 Center for Quality and Reliability of Production.

Thesis (MTech. degree in Business Information Systems.)--Tshwane University of Technology, 2009. / Software projects often fails due to poor estimates. These estimation problems often involve the under- or over-estimation of costs, the duration of the project and the complexity of the system. Project estimation comprises one of the major aspects of project management which either makes or breaks a project. Accordingly the aim of this research is to identify estimation problems, their causes and their impact on the success or failure of projects. The results indicated that the majority of the participants developers and clients have experienced estimation problems in certain of the IT/software projects that they have either implemented or developed. These problems have tended to impact negatively on the outcome of the projects. Based on the research findings and on suggestions from various participants, recommendations are made that could assist the developers and clients of software/IT projects to prevent these estimation problems. Accordingly these recommendations could contribute to more successful projects.

M.Ing. / Water demand prediction can be useful for future planning and has a significant economic effect on a city, town or suburb. There are numerous factors influencing water demand and therefore influencing the prediction thereof. The effect of each of these factors on the water demand is called the elasticity of that factor. The main aim of this study is to determine area and income elasticities of demand. This will enable the reader to predict water demand by taking stand size (area) and income into account. The stand value of each user was used as a surrogate for the income of that user. Another aim of this study is to compare average water demands for different cities and towns in Gauteng, South Africa with each other. Over 190 000 users' data were used for this study.

This report mentions some of the difficulties faced by labor estimators when predicting the labor necessary to produce complex weapon systems. Specific attention is focused on estimating the durations and frequencies of testing, troubleshooting, and retesting activities. Emphasis is placed on estimating in a logical manner while using factors based on subjective judgment.
