## 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
- = number of observations

*Memory*

The array storage required is
approximately 8(4*v* + (3 + *v*)*b* + *s*) bytes.
When you do not use BY processing, the array storage
required is approximately 8(4*v* + (4 + *v*)*s*) bytes.
*Time*

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