LinRegtIntervals
Catalog >
LinRegtIntervals X,Y[,F[,0[,CLev]]]
For Slope. Computes a level C confidence
interval for the slope.
LinRegtIntervals X,Y[,F[,1,Xval[,CLev]]]
For Response. 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.
X and Y are lists of independent and
dependent variables.
F is an optional list of frequency values.
Each element in F specifies the frequency of
occurrence for each corresponding X and Y
data point. The default value is 1. All
elements must be integers ≥ 0.
For information on the effect of empty
elements in a list, see “Empty (Void)
Elements,” page 232.
