Quality quandaries : Beware of autocorrelation in regression

• In the quality engineering context, the problem of trying to assess whether there exists a relationship between several inputs and an output of a process is often encountered. The main reason for spurious relationships between time series is that two unrelated time series that are internally autocorrelated sometimes by chance can produce very large cross correlations. Perhaps the safest approach to assessing the relationship between the input and the output of a process when the data is autocorrelated is to use prewhitening
