Regression
Analysis
of
Paired
Data
The
HP
48
can
fit
any
one
of
four
statistical
models
to
a
set
of
data
pairs.
Once
again
the
data
must
be
in
the
¥
DAT
matrix.
Example:
Using
the
same
data
as
the
previous
example,
calculate
the
correlation
and
covariance
between
the
CPI
and
PPI
variables
using
the
best-fitting
regression
model
(of
the
four
available).
Then
predict
the
PPI
value
for
a
CPI
value
of
8.5
using
the
calculated
model.
