MultReg
Catalog >
MultReg Y, X1[,X2[,X3,…[,X10]]]
Calculates multiple linear regression of list Y
on lists X1, X2, …, X10. A summary of
results is stored in the stat.results variable.
(See page 172.)
All the lists must have equal dimension.
For information on the effect of empty
elements in a list, see “Empty (Void)
Elements,” page 232.

MultRegIntervals Y, X1[, X2[, X3,…[,
X10]]], XValList[, CLevel]
Computes a predicted y-value, a level C
prediction interval for a single observation,
and a level C confidence interval for the
mean response.
A summary of results is stored in the
stat.results variable. (See page 172.)
All the lists must have equal dimension.
For information on the effect of empty
elements in a list, see “Empty (Void)
Elements,” page 232.
