I am a beginner with R (and also with the statistics) for which I hope to
I should do this non-parametric test on data I extracted from maps.
In practice I have a column that represents the landscape Dynamics of a
certain time period (there are 3 dynamics, each of them marked by the
number 1, 2 or 3) and the other column with the values of a topographic
variable (for example the slope) . In all, there are more than 90,000 pairs
Going to do the test in R, for all the dynamics and for all the variables,
I get out of the values of chi-square elevated (even in the order of
thousands) and a p-value always <2.2e-16 .... why? Where can the error be? in
the script or in the test approach?
Thanks in advance
