Hi,
I'm trying to fit a regression model where two of the coefficients are
constrained to be the same sign (could be either positive or negative).
This corresponds to truncating one of the distributions at zero either
above or below, depending on the sign of the other parameter. Based on my
understanding of the winbugs manual, it sounds like censoring the
parameter using I(0,) or I(,0) is not appropriate here. Does anyone have
any experience/advice on implementing a model with this constraint?
thanks,
sam cook
