st: TSCS: what model for N>T ??
Fellow Stata users,
I�ve been working on TSCS data involving 41 police force areas, and about 7
time periods (soon I hope to be 8). I�m theoretically interested in a fixed
effects model, because I want to see how variation within police forces is
impacting arrest rates over time (and Hausman tests suggest a fixed effects
model is appropriate).
However, is OLS fixed effects my only choice here? I have played a little
with a panel adjusted standard error (the Beck and Katz model). But while I
have seen published articles which use the PCSE model with a similar data
structure to mine (N a lot greater than T), I have since been advised that
this is not appropriate. This puzzles me a little, because I have also read
further that the Beck/Katz is actually more suited to N>T than other
approaches.
In short I�m confused. Help!
