Great work! Any reason to use adjusted price not returns ?

[@DataHeroes]

You can use any. Really depends what you are trying to predict

For the "fomat error" u can solve this fixing the pre.period by including one day after the treatment date.
Someting like this:
start

Fantastic work, really beneficial. One question: are there any other data package like series that can readily be used as a source of time series data? For example, import, export, GDP, etc.?

[@DataHeroes]

Unfortunately, none that I am familiar with

I keep getting 'data is not numeric,. What could be the problem?
