graphindI {IQCC} | R Documentation |
Builds the individual phase I Hotelling control chart.
graphindI(T2, m, p)
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. |
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.
Return a control chart.
