When
LinRegTTest
is executed, the list of residuals is created and stored
to the list name
RESID
automatically.
RESID
is placed on the
LIST NAMES
menu.
Note: For the regression equation, you can use the fix-decimal mode setting to
control the number of digits stored after the decimal point (Chapter 1).
However, limiting the number of digits to a small number could affect the
accuracy of the fit.
ANOVA(
ANOVA(
(one-way analysis of variance; item
F
) computes a one-way
analysis of variance for comparing the means of two to 20 populations.
The
ANOVA
procedure for comparing these means involves analysis of
the variation in the sample data. The null hypothesis H
0
: m
1
= m

k
is
tested against the alternative H
