Figure 3From: Improved variance estimation of classification performance via reduction of bias caused by small sample sizeLeast squares fitting for different sizes of N d . The variance σ dt 2 plotted against 1/N t , where N t is the number of test (holdout) samples used. The solid lines are the least squares fittings of the simulated average values for 1/N t . The dashed lines are produced by means of the analytical result in Eq. (2).Back to article page
