graphindII: Individual Phase II Hotelling Control Chart.

Description

Builds the individual phase II Hoteling control chart.

Usage

graphindII(T2II, m, j, t, p)

Arguments

T2II

A vector with the value of T2 statistic for one sample.

m

The number of samples generated previously in function dataindI.

j

The index of the current sample.

t

The maximum value of the x axis.

p

The dimension used previously in function dataindI.

Value

• Return a control chart.

Details

It builds the Hotelling T2 control chart for multivariate normal data (individual observations taken sequentialy); the control limits are based on the F distribution, and the covariance matrix estimator is based on the sucessive difference method.
