Context: Software development effort estimates are often inaccurate, and this inaccuracy cause problems for the clients as well as the providers. Consequently, we need more knowledge about the estimation processes, so that we can improve them. Objective: This study investigates how initial judgment-based estimation of work effort in software development affects subsequent, unrelated estimation ...

in this paper an efficient three- stage algorithm is developed for software production cost and time estimation. first stage includes a hybrid model composed of cocomo and function points methods to increase estimation accuracy. second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...

Background: Many comparative studies have been performed on effort estimation models. Linear regression (LR) and Estimation by Analogy (EbA) were often compared. The past research revealed that those comparative studies reported inconsistent results among performance measures. However, those studies seemed not to reflect actual or desirable study procedure. Aim: We aimed to examine performance ...

1 Draft submitted to ICSM 2002 Abstract Effort estimation is a valuable asset to managers in planning maintenance activities and performing cost/benefits analysis. Early estimates and accurate evaluations permit to significantly reduce project risks and to improve resource scheduling. In this paper we present an approach for an early effort estimation based on the knowledge of a fraction of the...

Capital-account liberalization was once seen as an inevitable step along the path to economic development for poor countries. Liberalizing the capital account, it was said, would permit financial resources to flow from capitalabundant countries, where expected returns were low, to capital-scarce countries, where expected returns were high. The flow of resources into the liberalizing countries w...

The US industrial sector displays heterogeneity among firms on the basis of their size: smaller firms exhibit a higher profit rate, lower survival probability and difficulty in accessing the capital market. A simple theoretical model that generates these features based on private information regarding managerial actions at firm-level production is developed and tested. Using a large panel of pu...

This paper applies current theory concerning the impact of irreversibility of investment, in order to test for the impact of uncertainty on investment expenditure for a middle income country. The contribution of the paper is unique in two respects. First, it employs dynamic heterogeneous panel estimation techniques not previously applied to investment functions. Second, it explicitly tests for ...

This paper investigates the effect of group-affiliation on the Indian corporate firms capital structure based on data of 875 Indian non-financial firms listed either in the Bombay Stock Exchange or in the National Stock Exchange, for the period 2002-2010. Among the three alternative estimation methodologies applied viz., (i) pooled OLS, (ii) generalized method of moments (GMM)and (iii) ‘lagged’...

Since 1973, the U.S. economy has shifted from a ability in the fishing industry have been conducted. The position characterized by abundant and low-cost enlack of studies on the substitution possibilities between ergy to one of rising energy prices and fragile energy energy and nonenergy inputs leaves a void in the apsupplies, periodically threatened by an unstable forpropriate information upon...
