Software cost estimation models

The importance of accurate cost estimates is discussed, and an overview of the existing methods for cost estimation is given. One class of models, namely, the parametric models, is then considered. The principles of parametric cost estimation models are examined, and an overview of such model is given. The existing models are compared, focusing mainly on the question of how accurate their estimates are. The advantages of the parametric models are described, and the state of the art is evaluated.<<ETX>>
