SETPRIOR Reset class prior probabilities of dataset
A = SETPRIOR(A,PROB,LABLIST)
DescriptionResets the class prior probabilities of the dataset A to PROB. PROB should be a vector of the length equal to the number of classes in A. In LABLIST, the corresponding class labels may be supplied. LABLIST may have only class names of the existing classes in A. Reset class names first by SETLABLIST if necessary. If LABLIST is not given, the order defined by the existing LABLIST for A (determined by [NLAB,LABLIST] = renumlab(LABELS)) is used. PROB = 0 makes all C classes equally probable: 1/C. PROB = [] is interpreted as using the existing class frequencies in A as prior probabilities. Note that these prior probabilities change, if the number of elements in A is changed, or its labeling.
