st: Question about generating the weight of WLS

[ayayi@uqtr.ca]

Hi everybody
- I have stata IC 10

-I have a panel data. To take in to consideration the considerable  
variation of the MFIs  (microfinance institutions) across countries on  
the empirical results, I resort to a weighted least squares with the  
weight being the inverse of the number of MFIs for the country in the  
database in a given year.
Can someone help me on how to generate the inverse of the number of  
MFIs for the country in the database in a given year and how to handle  
this WLS. Please find below an example  of the data
Thanks for your time and consideration
