Predictor - Version 1.0 Prediction support tool intended for software project managers who need to estimate the time needed for a new project. However, it can be used to estimate any attribute in the project database. Estimations can be done by the user directly, in which case Predictor acts as a decision support system, or by the program directly. In the latter case Predictor can use either a userdefined algorithmic model or a Case-Based Reasoning algorithm to create the estimation. Documentation and registration codes are available on the programs homepage.
