[R] discrete hazard rate analysis

[Joao Pedro W. de Azevedo]

Dear R users,

I have more of a statistical/econometric question than straight R one.

I have a data set with the discrete hazard rate of small firms survival on
400 counties over a period of 9 years. This data was generated using census
information from the VAT registration number of each one of these business. 

I would like to analyze the effect of regional factors (deprivation index,
real wages, average schooling, population density, etc) on the variation of
these hazard rates across counties over time.

I've done a search in the economic literature on firm survival and regional
economics, but I could not find any reference that would resemble the type
of data or the problem that I would like to explore. I would like to know if
anyone in the list has any suggestion of references that I might have missed
in economics, or if people on any other fields know of any references of
people looking at any data that might resemble this one (I don't know, but
maybe epidemiology might have regional level data that might look at similar
issues).

Of course I would also like to know which R commands could assist me on this
analysis.

Any suggestions will be much appreciated.

All the very best,

JP
