Parameters | Predictive Modeling | Custom Prior Probabilities

•

• 0.X, 0.Y ... 0.Z, represent the prior probability of each level and are numbers between 0.0 and 1.0,

• if the level is numeric or contains special characters, that level must be enclosed within single quotation marks (for example, ‘1’=0.2),

•

• The prior probabilities should sum to one (1.0). If they do not, all values are rescaled such that they do sum to one (1.0).

For example, if the class variable has three levels A, B, and C, with prior probabilities of 0.2, 0.2, and 0.6, respectively, then specify A=0.2 B=0.2 C=0.6, as shown below:
