Hi All,

I am currently using the world bank enterprise survey data for my PhD research. This is firm-level data and it consists of repeated cross-sections for 2006 and 2014 for one country.

Is there a way for stata to understand or read that this data is a pseudo panel? Ideally, I would like to group the firms by sector (either manufacturing or services).

Your assistance is appreciated.

Best regards,
Reem
