This series is terrific and I hope it will be returning very soon? Also, are these presentations available for download?

Could you tell which book you might be using, I'd like if it is introduction to econometrics by James

min: 9.20.. I guess I am lost here.. as I know more standard deviation determines the height and width of
the curve. When the standard deviation is large, the curve is short and wide; when
the standard deviation is small, the curve is tall and narrow. (high kurtosis)..did you mean that?
