Two Visually Meaningful Correlation Measures for Comparing Calculated and Measured Response Histories

Shock and Vibration, 1994
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 that is a ...
