SYSTAT Rectangular file C:\SYSTAT7\S209\GRAD.SYD,

The following commands estimate the regression model and save residual
diagnostics ("resid") and partial residuals ("partials") in
the file 'gradres.syd'.

SYSTAT Rectangular file C:\SYSTAT7\S209\GRADRES.SYD,

The next 3 commands create the partial regression plots; the options after the
/ are nonessential.  ("influence" requests an influence plot with the size of the
symbol proportional to the influence of a case; "stick" to have tick marks stick
out; "smooth=linear" to draw the partial regression line; "short" to limit the
regression line to the range of data on the X axis.)
>plot ypartial(1)*xpartial(1)/influence stick smooth=linear short

>plot ypartial(2)*xpartial(2)/influence stick smooth=linear short

>plot ypartial(3)*xpartial(3)/influence stick smooth=linear short
