Table 4.

Results of the significance test of ICA-T-SP method compared to the other methods using the one-sided paired t-test. The improvement is highly significant (p < 0.05) for all validations measures and tested methods but Pearsons correlation coefficient R² and BRMSE when compared with ICA-SP. In these two cases the improvement is of a low significance (p < 0.1).
