For non-parametric stability measures Huehn's method is being used. Huehn's paper(Euphytica, 47: 189-194,1990), on page 190, bottom left para, he clearly says that lowest value be given rank 1.
However, what rank should be given to the highest yielder? Is it 1 or the kth rank as per genotypes yields? It did change the interpretations when the ranking changed. Some papers give rank 1 to the highest yielder. Is it correct? Please advise.
Just do what he says and quote the his name for the test. Usually the lowest value is assigned a value of 1 in non parametric ranking tests and the highest is given the kth rank
Thanks Andrew Paul McKenzie Pegman . There are other papers which did the opposite and I was struck. Will go with your suggestion. Somehow, these non-parametric tests are undervalued and underutilized. They do come handy when the other models become inadequate.
