Dear students, 

as already announced you during today's class, tomorrow lesson is cancelled due to my institutional commitment. 

I have been uploaded two files (exercises) in the homework section concerning simple regression model.  I uploaded also a brief video lesson concerning today topics. Please, first watch the video and then try to solve these two exercises. 

In this way, you have all the materials to carry on all the points of the two assigned exercises. 

Thank you.
