R-sig-ecology peeps, I have been helping a friend run an NMDS and we started talking about the the goodness of fit statistic (GOF) to identify outliers. It got me thinking about this metric a bit more. I have always used exploratory analysis procedures, like normal qqplot, histograms, box plots, ect., to identify outlier in my data. So I have two questions regarding GOF: 1) can the NMDS goodness of fit statistic be used to identify outliers? And 2) is there a recommended threshold of the NMDS goodness of fit statistic that would identify outliers?
