Software Cost Estimation Through Bayesian Inference of Software Size.

Abstract

It s important for the program manager to understand the software life-cycle and development process. Multiple models of the life-cycle are examined and compared with the DoD software lifecycle. The Rayleigh equation and the resulting difficulty gradient equation of the SLIM software model are very powerful techniques for estimating development time, effort, and cost. To estimate the size f the new project a Bayesian inference technique is proposed. This technique is then applied using the SLIM model and the QSM data base. Keywords: Software cost estimation; Bayesian inference; Software life-cycle; Rayleigh distribution.
