<p class="MsoNormal">Hello dear group,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a question regarding the outdegree activity effect in directed networks. The manual describes it as:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The out-degree activity effect (with or without ‘sqrt’) reflects tendencies to actors with high out-degrees to send out extra outgoing ties ‘because’ of their high current out-degrees. This also leads to dispersion in out-degrees of the
actors.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But, as I see in the formula, it is just the squared amount of an ego’s outdegrees. Wouldn’t that rather test for an “inverse U-shape” effect of outdegrees, in a way that their marginal effect follows a curvelinear function, where they
first matter less, then more, then less again?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the same manner, how could the squareroot version of this effect, which is basically the squareroot of an egos outdegrees?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much in advance helping me solving my confusion.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best wishes<o:p></o:p></p>
