The probability for each observation and each group is calculated from the squared distance using the following formula:

To normalize the probabilities to sum to 1, Minitab uses the following formula:

### Notation

d (k, i) | squared distance for group k and observation i |

p (k, i) | probability for group k and observation i |

dmin (i) | smallest squared distance for observation i over groups |
