These stat blogs have been fun, to free up some time to pursue other items of interest, I may start tapering off at the end of the 1st quarter. Until then, I hope you've enjoyed them as much as I have, hopefully they've helped you evaluate the statistical long-term trends and have given you a different perspective to work with.

I'm leaving town this weekend, won't be back till mid-week, please try not to let the markets fall apart while I'm gone...

Take care…Jason
