I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code?

Currently, I'm using the Java libraries in the following manner

    SvmModel model = Svm.svm_train(problem, parameters);
    SvmNode x[] = getAnArrayOfSvmNodesForProblem();
    double predictedValue = Svm.svm_predict(model, x);
