Erratum

Upon publication of this article [1], an error occurred in the PDF presentation of the hat (WT) formula in ‘Concept of MDE genes and mean heterogeneity tests’ of the ‘Methods’ section on page 3. The corrected formula is shown below:

$$ \widehat{WT}=\frac{{\widehat{\mu}}_{i1}\mathit{\hbox{-}}{\widehat{\mu}}_{i2}}{\sqrt{\frac{{\widehat{\sigma}}_{i1}^2}{n_1}+\frac{{\widehat{\sigma}}_{i2}^2}{n_2}}} $$

The above formula has been corrected in the original article.
