  1. The values listed are \(100\,MSE(\hat {\rho }_{i})/MSE(\hat {\rho }_{{\boldsymbol {\mu }}})\) and are based on 10,000 repetitions. Each species of iris is in turn the target group. The MAMSE weights are calculated based on a global or pairwise strategy. Relative MSE are reported for each pairwise correlation, as well as for the correlation matrix in the case of global weights
