[Ipmpack-users] help with IPMpack

[Elena S.]

Hi,

I try to calculate CI (confidence intervals) for my stochastic population growth rate. I started with 4 IPM (four years of study), then I run the following function:

exp(stochGrowthRateSampleList(list(IPM9,IPM10,IPM11,IPM12),nRunIn = 100, tMax = 5000))

or the following ones, based on the IPMpack manual (Metcalf et al. 2014):

exp(stochGrowthRateSampleList(nRunIn=100,tMax=5000,listIPMmatrix=list(IPM9,IPM10,IPM11,IPM12),
                              listPmatrix=list(Pmatrix9,Pmatrix10,Pmatrix11,Pmatrix12), 
                              listFmatrix=list(Fmatrix9,Fmatrix10,Fmatrix11,Fmatrix12),
                              seedList=NULL,
                              densDep=FALSE))

and I obtained a stochastic lambda of 1.25, but, at the moment, I don't know how to calculate the confidence intervals.

Anyone can help me?

Thanks in advance,

best regards,

Elena
