When a large number of variables are input to the cluster analysis module, likelihood values can become prohibitively small. The algorithm automatically scales these values to avoid loss of precision, without invalidating the results in any way. The expert option ‘Scale Factor Exponent’ may be used to bypass this feature by using a specific value, e.g., 10, to multiply the probabilities.
