estatauxsub: Auxiliary statistics for the multivariate control chart with sub-group observations.

Description

This function calculate the auxiliary statistics necessary to build the control chart reference lines.

Usage

estatauxsub(datum, m, n, p)

Arguments

datum

The data set. Should be an array.

m

The number of sub groups generated previously in datasubI.

n

The size of each sub group used previously in datasubI.

p

The dimension used previously in function datasubI.

Value

• Return the values of the three statistics: a matrix with the means, mean of the means and mean of the standard deviation.

Details

To use this function it is necessary to have the information about the datasubI.

Examples

mu<-c(5.682,88.22)
Sigma<-symMatrix(c(3.770,-5.495,13.53),2)
datum<-datasubI(20,10,mu,Sigma,2)
estat<-estatauxsub(datum,20,10,2)
