[R] Seemingly Unrelated Negative Binomial (SUNB) estimation

[Elisa Lanzi]

Dear all,
I am trying to estimate a system of equations with a Seemingly Unrelated
Regression. However because of the characteristics of the data I'd like to
do it with a negative binomial estimation. Would anybody know how to
implement a Seemingly Unrelated Negative Binomial (SUNB) estimation in R?
Thank you in advance for your help.
Best regards,
Elisa Lanzi
