getcdfupdates: CDF of Updates of a Control Chart
In spcadjust: Functions for Calibrating Control Charts

Description Usage Arguments Value Methods (by class)

Consider running a control chart with given parameters with data coming from a given probability model. This function computes the cumulative distribution function (CDF) of the updates of the control charts as they would be computed by the method updates.

getcdfupdates(chart, P, xi)

## S4 method for signature 'SPCchart'
getcdfupdates(chart, P, xi)

## S4 method for signature 'SPCShew'
getcdfupdates(chart, P, xi)

`chart`	the chart to be used.
`P`	the probability model from which data is generated.
`xi`	the parameters of the control chart.

A function mapping one-dimensional numerical values into the interval [0,1], having all properties of a cumulative distribution function.

SPCchart: Standard method which simply first applies getcdfresiduals from the data model.
SPCShew: Computes the CDF of the updates taking into account if the chart is one-sided or two-sided.
