Is there anyway to create day wise previous data through Periodic function in SAS VA?

SKG — Wed, 28 Sep 2016 09:47:03 GMT

Hi Guys,

Is there anyway to create day wise data through Periodic function (like Relative Period, Parallel Period, Cumulative, Parallel, PeriodwithDate...) in SAS Visual Analytics?

An example:

I have dataset like this in LASR Server

Date Revenue

24-Sep-2015 $20

25-sep-2015 $10

26-sep-2015 $40

27-sep-2015 $50

28-sep-2015 $60

24-Sep-2016 $70

25-Sep-2016 $80

26-Sep-2016 $90

27-Sep-2016 $16

28-Sep-2016 $25

and i want day wise comparison current date to previous date...

Date Revenue Previous Revenue

24-Sep-2016 $70 $20

25-Sep-2016 $80 $10

26-Sep-2016 $90 $40

27-Sep-2016 $16 $50

28-Sep-2016 $25 $60

Yes, like I mentioned in your other thread the are periodic operators. Not sure if they cover all the scenarios you're mention.

Hi Linush,

There are only three specifics interval i.e _ByMonth_, _ByQuarter_, _ByYear_ but there were no any _ByDay_ interval option available.

For the outer interval you can use _ByYear_. But you are correct, you probably need a _ByDay_ for the inner interval.

Day-wise interval can be used when your inner interval is set to _Inferred_.

However, as I understand it there are some technical issues calculating day-wise data over time. If your operator has an offset (like your example with RelativePeriod would have) then we return missing values.

I think this is something we are working to improve for the future.

Thanks,
