Modification of: Error Log Analysis: Statistical Modeling and Heuristic TrendAnalysis

摘要

The original paper used 'traditional statistical analysis' to demonstrate thesuperiority of the proposed dispersion frame technique. The purpose was to distinguish between transient and intermittent errors and predict the occurrence of intermittent errors. This note shows that those traditional statistical methods were too traditional since they involved fitting a distribution to data which were not identically distributed. Appropriate statistical techniques for fitting models to such nonstationary data are briefly discussed, and reasons are proffered for the persistence of 'too traditional' statistical methods in the reliability literature....
