Dealing with gaps in data.

[Tom Leitch]

Hi, I'm having trouble getting my data in the right format. I'm working with weakly data values but in a daily format. I'm being told there are missing values and have tried to use the delta (7 days) command but Stata does not recognize this and gives me error messages in return. Would you be able to help me with this issue?

Thanks in advance,

Tom

delta() is an option to tsset or xtset, not a command. Either that's just a question of correct terminology or it's the answer. If it's not the answer, then I think you need to show example data and exact commands used, as we do ask (FAQ Advice #12).

That’s the answer, my fault with the mix up of terminology for commands. Thanks a lot and much appreciated
