Erratum

In the original publication of this article [1], a formatting field was mistakenly deleted, changing the entire composition of the first formula listed in the article.

The following formula is incorrect:

$$ \frac{R_{m \arg}^2={\sigma_{fix}}^2}{{\sigma_{fix}}^2+{\sigma}_{rand}^2+{\sigma}_{err}^2} $$

This should have been displayed as:

$$ {R}_{marg}^2=\frac{\sigma_{fix}^2}{\sigma_{fix}^2+{\sigma}_{rand}^2+{\sigma}_{err}^2} $$
