r-squared results are negative and more than 1 for bilateral gravity model

Dear Statalist,

I have estimated a gravity model with external instruments for possible endogeneity between cost and remittances. however the results of r-square are negative and more than 1 in some cases. Could anyone explain where might be the issue?

Thanks and Regards,
Junaid
