Damodar N. Gujarati

Basic Econometrics, 4th edition, written by Damodar N. Gujarati, i read some part of it this afternoon.

And with this i find Econormetics is not that hard to learn.

A right book makes it totally different .

So a right way we choose will make many things different too.

I even didn't notice the winter has came so fast when i get some fever lastnight. When i changed to a thick coat i find i should do this much ealier. I took two pills and it's ok this morning.
