Dear Statalists,
I am doing the research on some unexpected Initial Public Offering (IPO) events. Basically, with a sample of about 2000 firms, I first run the logit regression to identify the determinants of IPOs, where the dependent variable equals one if a sample firm is involved in IPO, and zero otherwise.

With the general logit regression results ready, I would like to investigate each specific IPO deal and to define whether it is an unexpected IPO or not. However, I feel a little bit confused on how to identify this by using the general logit regression results.

Therefore, it would be much appreciated if any kind suggestion could be provided.

Best wishes,
Cong
