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)

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 onedimensional 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 onesided or twosided.
