Hello all,<br><br>I am using BIOMOD to model some data, but I'm facing some errors that i can't seem to overcome.<br>
<br>As i tried to run the models on some of the populations, the following error showed up in R:<br><pre><font style="font-family: arial,helvetica,sans-serif;" size="2"><b><font style="font-family: arial,helvetica,sans-serif;" size="2">Error in nnet.default (x, y, w,...): </font></b></font><b style="font-family: arial,helvetica,sans-serif;"><font style="font-family: arial,helvetica,sans-serif;" size="2">initial value in 'vmmin' is not finite <br>
<br><br></font></b><span style="font-family: arial,helvetica,sans-serif;"><font style="font-family: arial,helvetica,sans-serif;" size="2">The error only happens when I try to model populations with 12, 9 or 7 individuals. When i model populations with 40, 26, 19 or even 14 individuals it works just fine.<br>
<br>So this error has to do with the sample size? Is there any way to solve this?<br><br></font></span><span style="font-family: arial,helvetica,sans-serif;"><font><font style="font-family: arial,helvetica,sans-serif;" size="2">I really appreciate all the help you can give me, since i am much of a newbie with modelling methods. <br>
