2. Re: Creating P Control Charts
Jason Howard Apr 18, 2013 4:43 AM (in response to Shawn Wallwork)Thanks for the reply! I greatly appreciate it. I was actually having difficulty in creating the Upper and Lower control limit calculated fields, but, I've been able to figure it out. It just took me some time to get the syntax right. I've included the UCL and LCL calculated field formulas that proved successful for me below in the event that someone might benefit from them in the future.
UCL = [P_Bar] + 3*(SQRT([P_Bar]*(1[P_Bar])/SUM([Sample])) )
LCL = [P_Bar]  3*(SQRT([P_Bar]*(1[P_Bar])/SUM([Sample])) )
These calculated fields also reference the Pbar calculated field, so, I've included that formula for reference as well.
P_Bar = WINDOW_SUM(( SUM([Sample_Y])) / WINDOW_SUM(SUM([Sample])))
Thanks!
