Although Charlie Rose made a cute quip, it was taken out of context in the article to make Summers look bad and fuel more government and Obama hate.

It was made at about 50 minutes into the video and discussing regulation. Charlie wiggled like a giddy school kid, finger pointing and trying to cut in, even though he was moderating, and waited 4 minutes to make the quip.

As much as it is obvious a lot of people and bloggers don’t like Summers, there should at least be some research and balance and proper context to be a story.

In time-series analysis, it’s almost always the case that time is plotted on the x-axis, and it’s frequently useful to notice that the value of a measurement changes over time (concentrations of atmospheric CO2 come to mind).

Given the possible relationships in this data (price-miles, price-year, miles-year), the strongest one is by far-and-away the relationship between the year and the number of miles driven–R^2 is .98, and so it’s perfectly appropriate to think of miles as a function of the year.

By: Curmudgeon Mon, 03 May 2010 14:04:13 +0000 @TWAndrews – The problem is that the X axis in data analysis and presentation represents the independent variable, and the Y axis the dependent variable. Rarely is it useful to say that a meaningful measurement is dependent upon the advancement of time.

Given the same information, I’d present it with time on the x-axis, miles on the y-axis, and use color or size to show the price dimension.
