mpcv.object: MPCV (multivariate process capability vector) object
In mpcv: Multivariate Process Capability Vector

Structure of mpcv object

An mpcv.object is a list containing the following elements:

`CpV`	the percentage value of the capability measurement component.
`PS`	the percentage value of the process shift component.
`PSvar`	the name of the variable which influences the process shift the most.
`PD`	the percentage value of the process distance component.
`PDvar`	the name of the variable which has the most negative influence on the value of the process distance component.
`coef.lo`	a named vector of leading coefficients of "lower" one-sided models; for the independent variable `NA` is returned.
`coef.up`	a named vector of leading coefficients of "upper" one-sided models; for the independent variable `NA` is returned.
