Measuring the Significance of Correlated Diagnostics Statistics
by Jeremy Penzer.
Problems involving calibration of sequences of correlated statistics arises in time series diagnostics. Critical values are required to locate unusual points from sequences of diagnostic statistics. We put forward simple criteria, which reliably identify significant outliers, level shifts and changes in seasonal pattern. The circumstances under which the correlation of sequences of statistics becomes important in determining critical values are discussed. These tests are applied to real data sets to detect behaviour previously overlooked.
