Panel data error

[Vivekkaushal]

how to solve multiple time ids issue in panel data analysis. I have multiple data for a given month which serves as a time id against the cross sectional id of location.

That's really a logic issue first - what do you want to do with the multiple ID? 

1. Account for it in the model somehow

2. Aggregate the data to have a single obs per time 

3. Pick one of the obs per time and use that one, ie first or last
