Multiple System Before vs. After Historical System Overview Analysis
After indicating we want to do a multiple system analysis, the following message will appear:
Choosing The Type of Analysis (Historical System Overview)
Indicate YES if you are comparing individual days (May 1st vs. June 1st)
An example would be if one was comparing :
System 1 (Before System) May 1st performance data
Vs.
System 2 (After System) June 1st performance data
Indicate NO if you are doing a historical analysis (May1-31st vs. June 1-30th)
An example would be if one was comparing :
System 1 (Before System) May 1st - May 31st performance data
Vs.
System 2 (After System) June 1st - June 30th performance data
On the next page, we will do a multiple period analysis
