Ken Garrett says January 6, 2016 at 2:39 pm It has never been tested much. Know what it is. If you have to apply it you will be guided and constrained by the information in the question. Log in to Reply

pbtpriyantha says November 16, 2015 at 6:18 am Dear Sir, Hi…. Can you please explain me what ‘s the relationship of coefficient of correlation (r) and Coefficient determination (r2= rXr) with Linear regression (y= ax+b)… Thanks in advance BR, Priyantha Log in to Reply

Very nice lecture, thank you!

tommy says

can we be asked to draw decision trees in p3?

Ken Garrett says

Yes – simple ones. See December 2012 Q4 (a)

It is explained in the lecture.
