Kendall Rank Correlation Let (X1, Y1), · · · , (Xn, Yn) be a bivariate random sample of size n. The Pearson correlation coefficient provides an optimal measure of the degree of association between the X’s and the Y ’s when the sample is drawn from a bivariate normal distribution. The Pearson correlation coefficient is reasonably robust for many other distributions as well. The Kendall correlati...

extracts of cotoneaster medicus, glycyrrhiza glabra, as endemic plants of iran, along with mixture of them were investigated for their antioxidant activities using 2, 2- diphenyl-1-picrylhidrazyl (dpph) reagent. uv-vis spectrophotometry method was used to evaluate the ability of cotoneaster and glycyrrhiza glabra antioxidant to scavenge dpph radical. the kinetic parameters such as rate constant...
