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.
