Abstract: dichoct dichotomizes varname at the specified centile and generates newvar containing the dichotomized values (0, 1). Dichotomizing a variable at a specific centile will not always result in an optimal split (for example, dichotomizing at values > or >= the centile value will yield different results -- especially if the value of the centile is frequent and is not exactly at the boundary of the interval including this value. dichoct chooses to include or to not include the centile value in the upper interval of the split (i.e. dichotomizes at values >= or > the centile value) so that an optimal split is achieved. "Optimal" means that the resulting percentages of the values of the dichotomized variable are closest to the desired percentages.
