Monte Carlo test on ENFA results problem
Dear Michela, Your graphical problem just makes me think that you have a very peculiar dataset. Have you most points at the exact same location, and just a few others? It would explain the graphs. As for the randtest call, it's hard to tell without the code you used and the outputs (but I understand there is none?). Could you please provide a reproducible example? Altogether, I really feel like the structure of your data will explain a lot... Best, Mathieu. Le 09/08/2012 05:49, Michela Giusti a ?crit :
Dear all, I am doing an ENFA and MADIFA analysis and I have problems with the randtest.enfa command of the adehabitatHS package. It does not work even if the pc works for hours. I also used the command of the old adehabitat version but the problem is the same. Do you know if there is an alternative command(s) that I can use to perfom a Monte Carlo test on ENFA results (I need to obtain the p-value)? Another question is about the graphs of the MADIFA test that I have attached. Can anybody help me with the problem in the figure madifa284.jpg??? Any idea? I also attached the figure relative to the scatter plot of the same madifa results (scatter_mad284) where it seems that there are not problems. Thanks in advance for any help, Bye, Michela
