Variance of Estimator of the Prediction Error Based on Blocked 3 * 2 Cross-Validation
This paper studies the variance of blocked cross-validation estimator of the prediction error recently proposed in the literature. A more accuracy representation of the variance is provided and the main theorem shows that there exists no universal (valid under all distributions) unbiased estimator of the variance.
