Re: [R] Interpreting the eigen value of a population matrix (2nd try)

[I've cc'ed this to the list because I think that it may be of value to other useRs, at least for archiving purposes.] Sorry, I did that work a long time ago in XLispStat (before I switched to R). The delta method and the bootstrap method for standard errors for eigenvalues are described in Caswel

Thanks for telling me that you could not get my message, I hope this work better... so my question was: I built a population matrix to which I applied the fonction eigen in order to find the main parameters about my population. I know that the first eigen value correspond to lambda or exponential
