Long-Term Study of Bias Jumps

-O'Dea, McMaster, and Heyer

We have studied long-term trends in the bias jumps. We found no significant evidence for any long-term change in either the frequency of the jumps, their mean/median amplitude, or in the dispersion of their amplitudes. Apparently, while the jumps are sporadic in nature, their long-term properties are stable.
