Hi, Stefano,

Thanks for your response. I updated cem (stata) and now it works well. It must be bcause my previous cem is old version.

Hi, cemers,

I am currently using cem to examine whether domestic firms being geographically close to foreign firms affects their exports (the geogrpahical proximity is the treatment). After cem (over a set of firm characteristics, such as firm size), I obtained the imabalance indicator:

Multivariate L1 distance: 1.9969533

However, the manual says that L1 shall be between 0 and 1. Can anybody help?

Cheers

Sun
