Dissertation- Bid Data

[rodcamb]

Hi,

For my undergrad dissertation I'm investigating the bids for franchises of the privatised British rail.

I only can get data for the winning bids, and would like to investigate what determines the winning bid- so some form of a probit model with binary outcome 1 or 0, except I only observe winning bids so only get the 1s.

Is there some econometric method I can use to correct for this???

Any help would be much appreciated, freaking out.

If you only observe data for winning bids, then you can't very well investigate the what makes the difference between a bid that wins and one that doesn't. Consider changing the question you are investigating.

Yeah, unfortunately realised that. Going to try and investigate something else. Will update you all on the mess of my life.
