The main purpose of this package is to juxtapose the different control limits obtained by modelling a data set through the COM-Poisson distribution vs. the classical Poisson distribution. Accordingly, this package offers the ability to compute the COM-Poisson parameter estimates and plot associated Shewhart and true probability bounds for a given data set.

For a given data set, the user can use the ControlCharts function to overlay any combination of the 3-sigma Shewhart CMP control chart, 3-sigma Shewhart classical Poisson control chart (c-chart), and the true CMP probability limits. The function also returns a list with relevant values relating to the control charts.
