(Maybe they do; I've gotten directions from one of the map services on a business trip that told me when I'd be paying a toll...)<BR/><BR/>The relationship isn't anywhere near 100% - I estimated about 10% of depreciation was due to miles; 90% due to age.<BR/><BR/>Will paste to other post now.M1EKhttps://www.blogger.com/profile/03650370583235985527noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-59233547004400823252008-02-22T16:37:00.000-08:002008-02-22T16:37:00.000-08:00No it doesn't have an r squared of 100.

You don't save remotely this much money by leaving your car parked in the driveway (as anybody with a car will tell you).M1EKhttps://www.blogger.com/profile/03650370583235985527noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-23611579402014591792008-02-22T10:41:00.000-08:002008-02-22T10:41:00.000-08:00These charts don't prove anything.

It's natural for car sales to inversely correlate with saving; it's natural for there to be the same correlation with televisions, clothes, and books, at least in the short term. When you look more broadly, the correlation evaporates. For example, Japan has more rail ridership and fewer car trips than the EU, but the EU has a higher savings rate.<BR/><BR/>As for the transit ridership chart, it doesn't show any national trend. The vast majority of American transit ridership has always been in New York. Right now the New York City Subway accounts for two-thirds of national heavy rail ridership. In the 1940s, when there was no DC Metrorail, it was even higher. And in the last fifteen years, rail ridership has been edging up while the savings rate has crashed.Alon Levyhttps://www.blogger.com/profile/12195377309045184452noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-3857676982207753042008-02-22T07:14:00.000-08:002008-02-22T07:14:00.000-08:00Interesting stuff.

I highly recommend the book Fooled by Randomness for examples on how statistics (like misapplying a causation argument) is so frequently misused.Anonymousnoreply@blogger.com
