The FASTCLUS Procedure |
If the value of the FREQ variable is missing or , the observation is not used in the analysis. The exact values of the FREQ variable are used in computations: frequency values are not truncated to integers. The total number of observations is considered to be equal to the sum of the FREQ variable when the procedure determines degrees of freedom for significance probabilities.
The WEIGHT and FREQ statements have a similar effect, except in determining the number of observations for significance tests.
