Compute the 9 × 15 matrix of sampling site means for BIOMASS and the 14 independent variables. Center and standardize the matrix of means and compute the correlation matrix of all 15 variables. Which independent variables appear to be most highly correlated with BIOMASS? Identify insofar as possible the subsets of independent variables that are highly correlated with each other. Are there any independent variables that are nearly independent of the others?
