Computational Resources

Let

v

= number of variables used in computing scores

s

= number of new score variables

b

= maximum number of new score variables in a BY group

n

= original input value

Memory

The array storage required is approximately bytes. When you do not use BY processing, the array storage required is approximately bytes.

Time

The time required to construct the scoring matrix is roughly proportional to , and the time needed to compute the scores is roughly proportional to .
