BRACE: Bootstrap Based Analogy Cost Estimation: Automated Support for An Enhanced Effort Prediction Method
Ioannis G. Stamelos, Emanuele De Angelis, E. Sakellaris · 2001
Estimation by analogy is a technique that has been proposed since a long time as a valid alternative to algorithmic cost estimation and expert judgement. On the other hand, it is widely accepted that public domain software cost estimation techniques need to be calibrated, i.e. properly adjusted, to historical project data, in order to produce accurate estimates for new projects. Another important requirement for any modern cost estimation method is the ability to produce interval estimates, not mere point estimates. Statistical simulation techniques may be used for both purposes. The paper presents BRACE, a software tool that supports the practical application of the analogy based method using a simulation approach, namely bootstrap.
