Baseline shift. Variance ratios for the testis dataset, under logarithmic transform with a baseline shift relative to the mean, for different values of a. Compared to the expected variance ratio under the null hypothesis of zero biological variance, and its 2.5% and 97.5% confidence limits (percentiles of the variance ratio with permutated data).
