6.1 Functional Description

Simple Regression Analysis generates simple linear
regression-based forecasts of the data elements that are
contained in the Capacity Planning database files.  Simple
Regression Analysis produces plots, either for a line printer
or for a color graphics device, that include historical data
observations and the forecasts of future values.  These
forecasts are based on least squares linear regression
models.

Simple Regression Analysis uses the SAS REG procedure to
fit a least squares trend line to the historical data
observations.  You may then use the model thus developed to
estimate future observations.
