Hi Gents,
I need to get the control limits from qcc function.
As follows:
qcc(MDI, type = "xbar.one")
Call:
qcc(data = MDI, type = "xbar.one")
xbar.one chart for MDI
Summary of group statistics:
Min. 1st Qu. Median Mean 3rd Qu. Max.
0.3266 0.4249 0.4371 0.4333 0.4451 0.4858
Group sample size: 1
Number of groups: 383
Center of group statistics: 0.4332557
Standard deviation: 0.01520659
Control limits:
LCL UCL
0.387636 0.4788755
I want to get LCL and UCL. It is possible ?
Thanks in advance,
Renata
