Section 4: Using Matrix Operations 1 35
This program has the following characteristics:
• If the entire program is keyed into program memory, the sizes
of n and p are required to satisfy n ^ p and (n + p )(p +

This assumes that only data storage registers RQ and Rj are
allocated. If subroutine "B" is omitted, then n ^ p and

Even though subroutine "B" uses the residual function with
its extended precision, the computed dependent variable data
may not exactly agree with the original data. The agreement
will usually be close enough for statistical estimation and
tests. If more accuracy is desired, the original data can be
reentered into matrix B.
