graphsubI {IQCC} | R Documentation |
Builds the sub group phase I Hotelling control chart.
graphsubI(estat, T2, m, n, p)
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. |
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.
Return a control chart.
