aic.nest: Nestedness of samples using AIC

In fossil: Palaeoecological and Palaeogeographical Analysis Tools

Description

Test if two empirical samples are drwan from the same or different communities

Usage

    aic.nest(comm1, comm2, base=exp(1))

Arguments

comm1, comm2	lists of abundance data from two empirical samples
base	base of the log used in the calculation of Shannon's diversity

Details

This function tests if two empirical samples are drawn from the same community, based on the AIC scores.

Value

returns two AIC scores, the first assuming the two empirical samples are drawn from the same distribution, the other assuming the two empirical samples are from different distributions

Examples

#for example, two different communities
a<-c(12,4,12,1,4,0,6,5,0,0,0)
b<-c(0,11,4,3,6,7,7,2,23,5,8)

#if the aic score is lower, it is the better model
aic.nest(a,b)

#from the same community
a<-c(5,6,5,6,5,6,5,6,5,2,1,1)
b<-c(2,3,2,3,2,3,2,3,2,1,0,0)
aic.nest(a,b)
