When developing a model, you might encounter a problem with setting the sample size in the Sample construction step. Some of the values exceed 100 percent and it is not possible to enter values that the Predictive Analytics Director considers valid. The same problem occurs in other steps where you can see numerical values.

Cause

The decimal separator for numerical values must be a dot, not a comma. The United States uses a dot for the decimal separator, while many other countries use a comma.

Solution
