I am new user of stata, kindly forgiven my ignorance and poor English.
My case is here. I have a data set consist 800+ company with other variable, such as total asset, total debt and many other from year 2010 to year 2016.
I have divide this 800+ company in to two group with a dummy variable (company do not being targeted for takeover during the study period (2010-2016)= 0, otherwise= 1).
However, I find out number of company is been targeted is only 50+ and the other side is about 700+.
So, I wish create a subset of data from this 700+ company(dummy=0) to compare with the 50+ company(dummy=1).
if it is possible included Total asset as one of the factor, such as new group 0 (dummy=0) having the same mean with group 1.
or just a random sample from group 0 with same number of company in group 1.
Thank you!
