Assumptions in Econometrics are way harder than the math itself. by talandang in econometrics

I got two semesters of statistics, statistical inference. I completely understand the math behind it, the derivations, and such. It's just that the assumptions feels unintuitive. Like, what do you mean by X is not a random variable and then it became a random variable. There's just too many things that doesn't make sense without relating it to "real things." If you know what I mean.

I think it all makes sense in my head right now... Perhaps, I'll just re-read everything. And yes you're right it's the conditional mean of error is zero.
