MultRegIntervals

Y X1
MultRegIntervals ,
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
97.)
All the lists must have equal dimension.
For information on the effect of empty elements in a list, see "Empty
(void) elements" on page 131.

MultRegTests

Y X1 X2
MultRegTests , [,
Multiple linear regression test computes a multiple linear regression
on the given data and provides the global F test statistic and t test
statistics for the coefficients.
A summary of results is stored in the stat.results variable. (See page
97.)
