Model Averaging through AIC

[Thiago_Timo]

Hello everybody,
I have recently used PRESENCE for analyzing models of occupancy data for medium to large size mammals.
I used percentages of vegetation type as covariates and as it was expected, a sort of models was shown to be feasible for describing the aimed relationships.
My question is what software I could use to average the models through the AIC weights.
Kind regards,
Thiago Timo.

Well, I guess the above question is no longer necessary, I am proceeding the averaging of models through excell.
What I`d like to know is, if it is possible to achieve model fit, the psis for species occurences and hypothesis test form the averages models in PRESNCE.
Thank you.
