the change in the effect of duration due to a unit
change in turnover when there has been a strategic
change and a ceo change.
I would have to have very good theoretical reasons
to introduce a four-way interaction though, because:
a) interactions eat huge amounts of power (i.e. you
are less likely to find a significant effect when
you should, or you need really really large datasets
to estimate these models), and
b) they are a nightmare to explain to your audience.
Hope this helps,
