Query: A Note on the Moments of Special Mixture Distributions, with
  Applications for Control Charts   Control charts can be applied in a wide range of areas, this paper focuses on
generalisations suitable for healthcare applications. We concentrate on the
effect of using mixture distributions as the possible shifts in the process
mean value. We give a closed formula for the expected squared deviation from
the target value between samplings. This observation can be utilised in finding
the cost-optimal parameters of the control chart.
