Abstract:

The increase in annual world crude oil production from 1880 to 1973 follows a pattern of exponential growth. In order to fit a linear model to these data, the oil production variable must be transformed by taking the natural log. A scatterplot of the log of oil production vs. year follows a strai...

The graph below suggests that the New Mexico highway fatality rate is highly related to the U.S. fatality rate. Other aspects need to be considered, however. Among these are the lagged New Mexico rate and the lagged U.S. rate, and perhaps time itself. Whatever model is finally adopted, the residu...
