Comparing Predictors

Abstract
This talk will involve introducing ‘a tool’ for comparing the performance of two models:
The case often arises when the performance of one predictor is compared to that of another (the performance of a Kalman filter compared to an exponential filter for CPU usage prediction, for example) Typically some form of f-test is applied based on the ratio of sum squared errors from both predictors to show that one is in fact better than the other. However, the underlying assumptions for the f-test are (in reality) always violated as the prediction errors are cross-correlated. This talk will introduce a test based on the difference and sum of prediction errors and an example with some additional details will be given.
Series This talk is part of the Computer Laboratory NetOS Group Talklets series.
