Dear all,
I am using MOStest in vegan to examine the hump-shaped of
a quadratic regression model.
In the manual of vegan, it mentions that the value of MOStest include
isHump.
My result showed the quadratic regression is hump-shaped according to the
p-value (nearly 0).
However, the value isHump did not show up.
Please kindly help where to find isHump.
Further, I do not understand the result of the function "plot"
for the MOStested regression model, after reading the manual of vegan.
(There are three graphs in the result, y-x plot, residuals and fitted
regression model, and cook's distance)
Please kindly share any references to interpret the graphs.
Thank you.
Elaine
code
library(vegan)
mos_test <- MOStest(BMN, DIS, family=gaussian)
plot(mos_test)
