I started with 4 IPM (four years of study), then I run the following function:<br><br>exp(stochGrowthRateSampleList(list(IPM9,IPM10,IPM11,IPM12),nRunIn = 100, tMax = 5000))<br><br>or the following ones, based on the IPMpack manual (Metcalf et al. 2014):<br><br>exp(stochGrowthRateSampleList(nRunIn=100,tMax=5000,listIPMmatrix=list(IPM9,IPM10,IPM11,IPM12),<br> listPmatrix=list(Pmatrix9,Pmatrix10,Pmatrix11,Pmatrix12), <br> listFmatrix=list(Fmatrix9,Fmatrix10,Fmatrix11,Fmatrix12),<br> seedList=NULL,<br> densDep=FALSE))<br><br>and I obtained a stochastic lambda of 1.25, but, at the moment, I don't know how to calculate the confidence intervals.<br><br>Anyone can help me?<br><br>Thanks in advance,<br><br>best regards,<br><br>Elena<br><br><br><br>_________________________________________________________<br>Dott.ssa Elena Sulis, PhD<br><font style="font-size:10pt;" size="2">Centro Conservazione Biodiversità (CCB)</font><br><font style="font-size:10pt;" size="2">Sezione Botanica - Dipartimento di Scienze della Vita e dell'Ambiente (DISVA)</font><font style="font-size:10pt;" size="2"><br></font><font style="font-size:10pt;" size="2">Università degli Studi di Cagliari</font><font style="font-size:10pt;" size="2"><br></font><font style="font-size:10pt;" size="2">V.le Sant'Ignazio da Laconi, 11-13</font><font style="font-size:10pt;" size="2"><br></font><font style="font-size:10pt;" size="2">09123 Cagliari (ITALIA)</font><font style="font-size:10pt;" size="2"><br></font><font style="font-size:10pt;" size="2">Tel: +39-0706753509</font><br><i>E-mail:</i> elenasulis@hotmail.it <br><i>Skype:</i> elena.sulis<br> </div></body>
