Abstract:

Two visually meaningful correlation measures are proposed for comparing calculated and measured response histories. One is an error index which is a simplification of RSS root-sum-square error factor, and the other is an inequality index which is a simplification of Theils inequality coefficient. The first compares the difference between the calculated and the measured histories to the measured history. The second compares the difference between the two histories to the sum of the two. The proposed correlation measures are compared to other existing measures, namely, Geers Error Factors, RSS Error Factor, and Theils Inequality Coefficient for ease of interpretation and visualization. Correlation measures, Error measures, Inequality measures, Computer code validation, Computer code certification, Comparison of calculations and measurements.
