<p class="MsoNormal" style="margin-bottom:12.0pt">I am writing regarding the centering of covariates in RSiena using the coCovar function.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I have 15 discrete variables for 41 actors representing their country of origin. It makes sense to me that these variables are not to be centered based on their discrete nature. However, the function coCovar
no longer allows one to input: centered = FALSE. At least the message returned is:<br>
<br>
Error in coCovar(country, centered = FALSE) : <br>
unused argument (centered = FALSE)<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Is someone able to assist me with this? Or provide more information on why I can center covariate variables?<o:p></o:p></p>
