    • A cusum procedure to detect deviations from uniformity in angular data 

      Lombard, F.; Maxwell, R.K. (Taylor & Francis, 2012)
      We propose a sequential cumulative sum procedure to detect deviations from uniformity in angular data. The method is motivated by a problem in high-energy astrophysics and is illustrated by an application to data.

    • Sequential rank CUSUM charts for angular data 

      Lombard, F.; Hawkins, Douglas M.; Potgieter, Cornelis J. (Elsevier, 2017)
      A cumulative sum (CUSUM) control chart has desirable properties for checking whether a distribution has changed from an in-control to an out-of-control setting. Distribution-free CUSUMs based on sequential ranks to detect ...
