Fig. 8. Analysis of the values provided by the mean and variance interval-based estimators
depending on the lengths of the traces: (a) - (c) average of the mean estimator, (d) - (f)
variance of the mean, (g) - (i) mean of the variance of the estimator, (j) - (l) variance of the
variance. In the four cases, the first column represents the average of 1000 simulations using
traces of 500 samples; the second column, of 1000 samples; and the third column, of 5000
samples. The values of the abscissa (1 to 8) respectively represent the interval widths: 0,
1/64, 1/32, 1/16, 1/8, 1/4, 1/2 and 1.
