## Warning!

Warning! Excel 97 (and almost all other statistical software and textbooks) define Residuals the same way as in this course: Residual = Observed value – Fitted Value But Excel 2000 uses Residual = Fitted Value – Observed Value Result: Residual Plots from Excel 2000 are upside down!.

## Lesson 81

Lesson 81. Using natural logarithms. Natural logarithms. When the base is e , the logarithm is called a natural logarithm e x = a means ln a= x. Inverse properties of logarithms. e ln x = x and ln e x = x where x>0.

## LOGS and LN and e

LOGS and LN and e. 11 2x = 102 x-1 Log 11 2x = log 102 x-1 2x Log 11= (x-1) log 102 use distrib. Prop. 2x log 11 = x log 102 - log 102 group x -x log 102 - xlog 102 2x log 11 – x log 102 = -log 102 factor out x x(2 log 11 -log 102) = -log 102 divide.
