graphindI: Individual Phase I Hotelling Control Chart.

Description

Builds the individual phase I Hotelling control chart.

Usage

graphindI(T2, m, p)

Arguments

T2

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

m

The number of samples generated previously in function dataindI.

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 : m samples of size n=1) used in retrospective / validation analysis (phase I) ; the control limits are based on a beta distribution, and the covariance matrix estimator is based on the sucessive difference method.
