(a) Correlation coefficient between [E]n and [Ta], [Td] of n − 3 to n + 2 SCs (total 12 parameters) is shown for ws = 9, 11, and 13. (b) Correlation coefficient between [E]n and test parameter [Ttest]n is shown with corresponding number of variables used for estimating the [Ttest]n. The combination C1 shows a correlation coefficient almost identical to that shown by the other five test parameters, but with the least number of variables. This optimum combination is preferred over the other five combinations.
