I have a dependednt variable "probability of informed trading" (PIT) and I
want to find the determinants of this variable. Since PIT is a probability i
thought i need to run Probit regressions. The problem is that I have around
40,000 firm-years and PIT can take any value betwen 0 and 1 in each of these
firm-years. The probit examples that i saw usually have more than 2 and less
than 10 categories. But, in my case i would say i have around 40,000
categories.. how do i deal with this problem?
Once i do the probit analysis in a right way how could I find the marginal
effects?
I would be more than grateful, if soemone could help me.
thanks,
-h.
