In this article the number "15" in the Bin_Freq equation in page 8 must be replaced with "150". Replace the epsilon in the equation with quotation marks in page 9. Given here are the correct equations.

$$\begin{array}{cc}\mathrm{BIN}\_\mathrm{Freq}=&\;\qquad ``<150\mathrm{" if\ weekly\ frequency\ from}\ 75\mathrm{ \ to}\ 150\ \mathrm{ minutes}\\& ``\ge 150\mathrm{" if\ weekly\ frequency\ over}\ 150\ \mathrm{ minutes}\end{array}$$
$$BIN\_ID=\left\{\begin{array}{l}''<40''if\;aged\;less\;than\;40\;years\\''\geq40''if\;aged\;greater\;than\;\;or\;equal\;to\;40\;years\end{array}\right.$$
$$BIN\_Renda=\left\{\begin{array}{l}''<\mathrm R\$\;8\;\mathrm{thousand}''\\''\geq\;R\$\;8\;thousand''\end{array}\right.$$

The original article has been corrected.
