-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi
I want to use the package tgp with its sens() function to cunduct a sensitivity analysis of an ecological simulation model and six independent input parameter. I conducted 10.000 simulations based on a Latin Hypercube design to sample the whole parameter range. Now I want to use the sens function to conduct the sensitivity analysis. I use the following call: SA <- sens(X = X, Z = Z, nn.lhs = 600, model = bgpllm, verb = 2) where X are my 6 input parameter, and Z is the response variable. My problem is, that I get a X[,1:6]-matrix is not of full rank error. I must admit ignorance, as I neither know what a "matrix of full rank" is, and how I can fix this so that I can conduct a sensitivity analysis by using sens(). Any help is appreciated, Thanks, Rainer - -- Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl. Phys.
