• ARIMA ("Box-Jenkins") modeling
• exponential smoothing
• regression with first-order autocorrelated errors
• seasonal decomposition
• spectral analysis
• X11 ARIMA modeling

Since graphical representation is an important part of this package, it is recommended that you use the X-Windows version of SPSS under UNIX if at all possible when using Trends procedures.

To run a demonstration program of the Trends package, start SPSS release 6.1 or higher and 'include' (ESC-3) the file /usr/usc/spss/default/demo/demotrd.sps into the SPSS Manager, or run it as follows:

spss -m /usr/usc/spss/default/demo/demotrd.sps > trends.out

/usr/usc/spss/default/demo/demotrd.ref

to see if everything operated correctly.

To run a demonstration program of the Tables package, start SPSS release 6.1 or higher and 'include' (ESC-3) the file /usr/usc/spss/default/demo/demotab.sps into the SPSS Manager, or run it in batch mode

Note that when running demotab.sps in the Manager, you will need to delete all lines that begin with /**** before you run the program. These are comment lines, and the interactive Manager doesn't process them correctly.

To run the program in batch mode, do the following:

spss -m /usr/usc/spss/default/demo/demotab.sps > tables.out

/usr/usc/spss/default/demo/demotab.ref

to see if everything operated correctly.

• profiles for use in conjoint studies
• four different models for conjoint analysis
• graphic summary of conjoint results
• optimal scaling techniques covering:
  • two-way correspondence tables
  • multiway contingency tables
  • comparisons of sets of variables of mixed measurement levels
• high resolution plots (under X-windows)

spss -m /usr/usc/spss/default/demo/democat.sps > categories.out

/usr/usc/spss/default/demo/democat.ref

to see if everything operated correctly.
