How about -nlsur- for two Poisson models, with interactions as
appropriate? I don't know about your theoretical model though--why
did DuPont drop petroleum and textiles in the last decade? Is sector
fixed? Why did Monsanto switch from chemicals to
biotech/patent-lawsuit between 1997 and 2002? Yes, old companies plow
token money into PR-rich displays of social responsibility, but they
can also retool entirely. What sector is Philip Morris or RJR (now, a
decade ago, two decades ago, etc.)? Size is also endogenous. The
whole strength v. weakness thing is a bit fuzzy.
