The original HTML version of this Article contained a typographical error in Equation 1.

$$y= \frac{100}{1+ {e}^{\left(x,-,(,\frac{a}{\theta },)\right)}}$$

now reads:

$$y= \frac{100}{1+ {e}^{\left(x-(\frac{a}{\theta })\right)}}$$

This error has now been corrected in the HTML version; the PDF version was correct from the time of publication.
