 to the corresponding standardized mean differences, when one of the two variables is dichotomized. Arguments <code>n1i</code> and <code>n2i</code> can be used to denote the number of individuals in the first and second group created by the dichotomization. If <code>n1i</code> and <code>n2i</code> are not specified, the function assumes <code>n1i = n2i</code>. This function is simply the inverse of <code>transf.dtorbis</code>.</p></li>
