Use of Multivariate Regression Analysis and Simulation for Defect Prediction

This white paper discusses the use of Multivariate Regression Model, instead of the Empirical Model used earlier, for prediction of defects in a project. A large variation between the number of actual defects and predicted defects was the key reason behind moving from Empirical Model to the Multivariate Regression Model. Once the Multivariate Regression Model was deduced, Monte Carlo Simulation technique was used to check its reliability. Using the simulation technique, the Deterministic Model was essentially converted into Stochastic Model. The benefits of using Monte Carlo Simulation technique are also discussed in this white paper.
