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 H0: m1=m2=...=mk is
tested against the alternative Ha: not all m1...mk are equal.
ANOVA(list1,list2[,...,list20])
In the example:
L1={7 4 6 6 5}
L2={6 5 5 8 7}
L3={4 7 6 7 6}
