Unfortunately, this is only a statistics class and not coding, and I have a question about how SAS works. I know how to properly create an xbar and r chart that correspond with one another. Yet I was wondering how do I then add a second group of data which is my phase 2 on an already existing control chart with preset limits from phase one data?</P> Mon, 21 Mar 2022 16:15:34 GMT https://communities.sas.com/t5/Statistical-Procedures/Xbar-and-Rbar-phase-1-and-2/m-p/803135#M39479 Jweinstein2001 2022-03-21T16:15:34Z https://communities.sas.com/t5/Statistical-Procedures/Xbar-and-Rbar-phase-1-and-2/m-p/803138#M39480 <P>See this example of using PROC SHEWHART with multiple phases</P> <P>&nbsp;</P> <P><A href="https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.4/qcug/qcug_shewhart_sect500.htm" target="_blank">https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.4/qcug/qcug_shewhart_sect500.htm</A></P> Mon, 21 Mar 2022 16:27:15 GMT https://communities.sas.com/t5/Statistical-Procedures/Xbar-and-Rbar-phase-1-and-2/m-p/803138#M39480 PaigeMiller 2022-03-21T16:27:15Z
