WitrynaA Note on Statistical Significance of Scalogram KARL F. SCHUESSLER, Indiana University In his recent book on measurement, W. S. Torgerson states that one limi-tation of Guttman's method of scaling resides in its incapacity to test statis-tically whether the cumulative scale model is a good fit (2). The Guttman scale Witryna7 maj 2008 · The analysis of the scalogram as the instantaneous frequency estimator is performed for any FM signal regardless of the mother wavelet. Accurate expressions for the bias and the variance of the estimator are derived, and reveal that the bias and the variance are signal dependent.
