<p class="MsoNormal">Dear all,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I want to show this variograma to you and ask about the
meaning.<span style=""> </span>These are data of abundance of
a tree species in the forest. I took the values (abundance = # individuals) and
transformed this abundance with root square (to minimize the variance) for each
point. I have 520 point from the forest, many of them with zero because the
species was absent. This variogram means that there is no spatial pattern?. I fitted
this variogram with corSphere or corRatio models to get these parameters, range
and nugget. I choose a model with base on Akaike Information Criterion (AIC). I
would like to use these values (range) for my results, but I do not known if I
am doing right this. I just want to hear your opinion.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks a lot for your help</p>
