Many of the variables are self-reported and measured with error. No way does any kid know the exact “average time spent per day talking on a mobile phone on a typical weekend day”, for example. This will increase uncertainty, and possibly bias, in effect estimates. Should we try to account for this?
This paper is a useful place to go to start thinking about these issues if we want to.
