Dear Andrew,
if i understand your code correctly, you first find a signifant
rda(abund~dist), confirmed by NMDS ordination, but
then you cannot find significant correlation between the residuals of
a linear model (abund~dist).
You may want to have a look at Dray et al 2012 "Community ecolog
Hi Listers,
I am trying to better understand how spatial autocorrelation is determined.
I have attached 2 txt files one is a fish species x sites abundance table
and the other is a distance file with the lat and longs for each site
(converted to cartesian coords). I have run the tests for spatial
Hello.
Recently, I started to develop regression models using spatial data. In
particular, I've been developing mixed-effect models. My data requires to
take into consideration spatial autocorrelation, so I decided to use the
corStruct function in the nlme library.
Once I built a variogram plot t
