I would like to build a calculated metric to get the sample standard deviation of Revenue per visit in Omniture as it is required to calculate statistical confidence. Ideally, this metric would make it so I would not have to pull from data warehouse to calculate confidence intervals and could do this in real time.
Is this possible?
Solved! Go to Solution.
I've gone through all of that documentation in great depth, but haven't had any success using the Std. Dev function to get a sample's std. deviation at a visit level.
When I compare two samples, it either shows the same value or zeros for both.
Just want to bump this up. I have the same question and have not been able to find a solution. The idea of having to resort to DW every time seems a bit inefficient.
Revenue is one of the metrics that does not follow normal distribution (aka bell curve). This is why the StdDev of RPV may not make any sense.
Could you share what scenario you are working on? — if you are running an A/B test, Target (or other tools) should have all required metrics in their UI.
Hey Andrey -
Scenario is evaluating the confidence level of the difference in RPV observed in an A/B test. One of the required metrics in the excel file from Adobe is sum of revenue squared. I'm trying to find a way to do this in workspace without needing to request a DW report every time. This gets time consuming when we are trying to evaluate the RPV for multiple tests. Any thoughts?
The question is why do you want to evaluate that in AA rather in the the A/B test UI?
P.S.: Square and Square Root can be built in the Metric Builder.
Jumping back in here, the easy answer for desire to do this in AA vs. Target UI is that the Adobe Analytics UI is just outright more user friendly for monitoring and analysis purposes, and some basic expectations are not met.
These are, to my understanding, features on the road map for AA but I would like to reiterate that their current absence is quite frustrating in A/B test analysis/monitoring and their addition would be greatly appreciated.
