I'm really hoping to see what your valuable expertise suggests and otherwise, how I should rephrase my question.

Column 1 with just controls and year dummies.

Do not include controls for the alliance.

Industry (SIC 2 digit) and year dummies.

Financial characteristics of the focal firm.

In general, it's a loop over the possibilities using forvalues or foreach, but the shortcut is too easy not to be preferred in this case. Indeed, that is the usual definition of dummies. It is almost always more useful to create them directly as 1 or 0. Note: dummy_2012 omitted because of collinearity. Say the ROA in 2013 is 0.78 and that year dummy is set to 1 (event occurred in that year) how do I make sure that stata includes the 0.78 of that year? Should I add interaction variables for every year dummy so that Stata does 0.78*1 (for example)? How do I make sure that stata recognizes that the dummy year variables are connected to the correct year. I have set up the variables in stata but I am struggling with operationalizing the dummy variables. My thesis supervisor told me to run the regression as mentioned below.

I'm running a logistic regression using the logit command. 59200363 (fraction of variance due to u_i)ĭear Carlo. Group variable: idcode Number of groups = 4,711Ĭorr(u_i, X) = 0 (assumed) Prob > chi2 = 0.0000 Random-effects GLS regression Number of obs = 28,534

Time variable: year, 68 to 88, but with gaps

Stata 13 for dummies
