Table 4.

Classification results from repeated 10-fold cross-validation and repeated double cross-validation of urine samples from patients with prostate cancer and patients with haematuria and or prostatic symptoms. LDA = linear discriminant analysis; and SVM-P = support vector machine; and CI = confidence interval of mean values.
