Following the publication of the original article [1], the authors identified an error in the equation. The correct equation is given below.

The incorrect equation:

$$t_{{(n - 2)}} = r_{{(\cdot)}} \sqrt {\frac{{n - 2}}{{1 - 0.5r_{{(\cdot)}}^{2} }}}$$

The correct equation:

$$t_{{(n - 2)}} = r_{{(\cdot)}} \sqrt {\frac{{n - 2}}{{1 - r_{{(\cdot)}}^{2} }}}$$

The original article [1] has been corrected.
