Questions about regression

[Markus Henriksson]

Hi,

Im currently working with some data that contains with types two types of companies SPACs and IPOs, the data of their returns and other variables are merged.
The SPACs that I am studying have been assigned a 1 in a column, and the IPOs have been assigned a 0, now im trying to come up with a way so that i can make a regression where the listing type is a dummy variable.
The goal of the regression is to see whether any of the variables I have gathered play a role in the companies stock performance, and to what degree. Im also thinking about some kind of interaction variable between the two listing types.

I havent used stata for 2 years, so my knowledge on stata is a bit rusty, to say the least.

Any help/input would be greatly appreciated!

Im also thinking about some kind of interaction variable between the two listing types.

regress stock_performance i.listing_type##i.other_variable

More generally:

Markus:
welcome (back?) to this forum.
As an aside to Joseph's helpful guidance, are you dealing with a cross-sectional or a panel dataset?
