There are upper and lowerbounds of the Bayes error as well as its determination in case of one dimension and multidimensions. Based on the proposals for estimating of probability density functions, calculatingthe Bayes error and determining the prior probability, we establish an algorithm to evaluateability of customers to pay debts at banks. This algorithm has been performed by the Matlabprocedure that can be applied well with real data. The proposed algorithm is tested by the realapplication at a bank in Viet Nam that obtains the best results in comparing with the existingapproaches.展开更多
