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 |

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

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