The Raj Jain book I already have. I'm very proud of that one! I managed to find a $100 book for $33!!! from a used book store and it was brand new! I'll look for the other one.

As much as I love Lex and Toon's "Applied Mathematics..." book, it is not a statistics book. Nor is Shallahamer's "Forecasting..." book. For a good intuitive introduction to statistics, I recommend putting $11 down on this one: http://www.amazon.com/Statistics-Manual-Edwin-L-Crow/dp/048660599X. If you want a really good book with a focus on statistics for performance analysts, use http://www.amazon.com/Art-Computer-Systems-Performance-Analysis/dp/0471503363/ref=sr_1_1?ie=UTF8&s=books&qid=1236912261&sr=1-1.

I continue to discover that I should have signed up for those stats classes back in the dark ages of college. I already have some cap planning books that are full of incomprehensible symbols and formulas. I almost need a how to for performance analyzers with regard to stats. I do some play stuff now with avg and std dev and slope and things but nothing complicated. Any suggestions you have would be appreciated. John
