Hi,

I want to try the following regression
ln(Y1) = [X1, 0] + [error11 error12]
ln(Y2) = [0, X2] + [error21 error22]

I am using this as an alternative to a Seemingly related Regression count
model, for which I may have to write my own code.

However, there are a few zeros in Y vector. Because of this, I am losing
about 900 observations. Can you suggest some possible ways to rescale the
zeros to
minimize the number of observations lost?

Thanks,

Prabhu
