CHAPTER 12
A note on computing with SAS (Version 9):
The SAS GENMOD procedure is used for fitting the Poisson regression models of
Chapter 12. This procedure is very general. It can also be used for t

6.1 (a) The Minitab output of the three regressions is shown below.
In the model involving x 1 alone, the hypothesis 1 = 0 can not be rejected. This
indicates that x 1 by itself is not impor

A note on computing in time series situations
The Minitab software is used here for calculating the autocorrelation function of time
series observations and for fitting the autoregressive i

A note on computing with SPSS (Version 11.5):
We use the SPSS software to fit the nonlinear regression models of Chapter 9. SPSS
works like a spreadsheet program. We enter the data into the

Many excellent computer programs are available for plotting the data and for carrying
out the regression calculations. Here we use S-Plus, R, Minitab, SAS, and SPSS. Most
programs work the s
