IQCC (version 1.0)

graphsubI: Sub group Phase I Hotelling Control Chart.

Description

Builds the sub group phase I Hotelling control chart.

Usage

graphsubI(estat, T2, m, n, p)

Arguments

estat

The values of the auxiliary statistics. Should be a list with a matrix with the means, mean of the means and mean of the standard deviation.

T2

The values of the T2 statistic. Shoul be a matrix.

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 a control chart.

Details

It builds the Hotelling T2 control chart for multivariate normal data (m sub-groups /samples of size n>1), used retrospective /validation analysis (phase I); the control limits are based on the F distribution.
