Bias-Variance Estimator is a software tool that can be used to understand the contribution of two components of the prediction errors, namely, Bias (or systematic) error and Variance (or random) error, which are obtained from the developed model. This tool employs ‘bootstrapping’ as a re-sampling technique.
