In a recent May 2007 IEEE TSE article, Kitchenham et.al. explored effort estimation and found contradictory evidence about the value of crossvs within-company data. Those contradictory results may have been the result of effort estimation features, some of which are subjective in nature. Static code features are different than effort estimation features. They can be generated in an automatic, r...

This paper discusses a model for effort estimation. This model focuses on minimizing effort variance by enhancing the adjustments made to the functional sizing techniques. A special focus is made on the adjustment factors which reflect the application’s complexity and actual environment in which this application will be implemented. We introduce the idea of grouping the adjustment factors to si...

A software vendor sometimes contracts the maintenance of a software product that other software vendors gave up maintaining due to costs etc. In such case, the vendor must estimate costs of maintenance before contracting. However, due to lack of an objective measure, an expert estimates the cost on the basis of his/her experience. We will propose some metrics for estimating maintenance effort. ...

Cost estimation process becomes a crucial factor in any software development project. An effective software estimate provides the information needed to design a workable software development plan. An effective software estimate provides important information for making project decisions, projecting performance and defining objectives and plans. Without the proper guidance in a project, the resu...

Estimation of cost and time to develop a software product P is a well known problem. Among the possible ways to do it is analogy with old finished projects. We describe an experiment using different versions of the Fuzzy c-Means algorithm, to find projects similar to P . Then the information about these projects is used to estimate the effort needed to build P .

objectives: the present study aimed to provide an estimation of the current financial burden of renal transplantation therapy for insurance organisations.methods: an excel-based model was developed to determine the treatment costs of current clinical practice in renal transplantation therapy (rtt). inputs were derived from ministry of health and insurance organizations` database, hospital and p...

One of the most important processes in the early stages of construction projects is to estimate the cost involved. This process involves a wide range of uncertainties, which make it a challenging task. Because of unknown issues, using the experience of the experts or looking for similar cases are the conventional methods to deal with cost estimation. The current study presents data-driven metho...

In this paper, we study the role of price correction in estimating the impact of price subsidies and anti-poverty cash transfer schemes on poverty in Tunisia. Three types of price corrections are considered: (a) no corrections; (b) living standards deflated by spatial Laspeyres price indices; (c) living standards deflated by true price indices that are estimated from a quadratic almost ideal de...

Pricing series reflect multiple decisions (e.g., regular pricing and discounting) often made by multiple decision makers. For example, temporary price reductions (high frequency price changes) can be used to price discriminate in the short run, while regular price adjustments (low frequency price changes) reflect more strategic or long-term goals. It is therefore not implausible that the “react...

This paper attempts to explore website evaluation measures specifically for information driven website such Municipal electronic government website toward website credibility and user engagement. Despite overwhelming of information source in online environment, the role of government website as a prominent government information provider becomes less preferred. Even, rapid development and conti...
