example.yaml throws exception KeyError: 'ME' using pandas

[lkimmer]

Hello!

First of all: Thank you for the package! Lpagg is exactly what I need. Unfortunately I could not get it to run on the first go.

What I did:

• Installed the package via anaconda as recommended
• Downloaded the project as a zip file and unpacked it
• Started lpagg via command and selected the downloaded example.yaml
