Builds the individual phase II Hoteling control chart.
graphindII(T2II, m, j, t, p)
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. |
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.
Return a control chart.
