4. A class's prior may be calculated by assuming equiprobable classes ( i . e ., priors = 1 / ( number of classes ) ), or by calculating an estimate for the class probability from the training set ( i . e ., ( prior for a given class ) = ( number of samples in the class ) / ( total number of samples ) ).
