Hello!

I am a real beginner with Stata and would like to know if I am doing the right things, I am doing research on panel data of venture capital investments done in start-ups. It would be great if someone could let me know if I am choosing the right regressions for this:

IV: Investment amount
DV: Start-up performance, measured by;
  • Going public (Yes/No)
  • Employment growth rate
  • Measured after the 1st investment date + 5 years and +10 years
Moderator 1: Industry Relatedness
  • Measured from 1 to 5 (1 being no relatedness and 5 fully related)
Moderator 2: Investment Stage
  • Measured by Early or Late Stage, Early stage being 1 and Late being 0
Regression types:
IV -> DV Going Public : xtprobit
IV -> Growth rate : xtreg
Moderator 1: Interaction variable added Investment amount x Relatedness xtprobit & xtreg
Moderator 2: Interaction variable Investment amount x Investment stage xtprobit & xtreg
Control variables: industry_growth_rate, industry_size, total_funding_received, cvc_parent_size

Question: How can you let Stata do the analysis from the first investment done in the company, or is this done automatically by Stata? Because I also have panel data from before the first investment.


Thank you very much for your guidance!
