How to make date as an index in timeseries analysis if I have duplicate dates for each item and store in dataset
How are you! First off, why do you need de time as index, maybe you can reconsider that idea?
Anyway using datetime should work and the chances to get a duplicate record is minimal
In timeseries analysis I want to set date as an index but one date has 500 entries 50 for each item and 10 for each store. In such case how can I make date as an index.
