You can load each type of range separately or you can specify the range type with the greatest number of parameters and load all types together. Other rules are.
Cumulative probabilities are supported for all but sloping ranges.
Blank probabilities are interpreted as a relative probability of 1.0.
For continuous connected ranges, for either endpoint values or probabilities, if the starting cell is blank, the previous end value is used as the start for this range.
When you load a discrete value that exists in the table already, its probability is incremented by 1. For continuous ranges, this is not allowed; an error message about overlapping ranges opens.
Note: | In versions of Crystal Ball earlier than 11.1.1.3.00, ranges or values with 0 probabilities were removed. Sloping ranges with Height of Min. and Height of Max. equal to 0 were also removed. The current rules are as follows: In the simple view for weighted values, if users enter a probability of 0 for a value, the users are prompted about deleting the value. For other types of values, 0 works as before to delete the range or value. In advanced (table) view for weighted values, if users enter a probability of 0 for a value, it is ignored (or added, which is the same thing). For other types of values, 0 works as before to delete the range or value. If a custom distribution was created with unlinked data in a version of Crystal Ball earlier than version 11.1.1.3.00, the frequency distribution does not change when the model is loaded in Crystal Ball version 11.1.1.3.00 or later. However, if the input range was linked for a custom distribution, the frequency distribution is updated according to current rules. All new custom distributions, linked and unlinked, are evaluated according to current rules. |
