which statistical approach is used to measure the similarity of a sine wave what is the metric directional movement does it take to find the degree of similarity of the sine wave how to compare time series using a sine wave how to use statistical similarity in time series to predict trends? how to do directional movement which is a statistically similar sine wave how to determine the degree of similarity how to find the similarity of the sine wave how to do directional movement in data how to find the degree of similarity between time series how to measure similarity between sine waves how to predict directional movement of sine waves how to determine directional movement from a sine wave which of these is more accurate directional or sine waves or euclidean how to measure directional similarity of a time series how to determine degree of similarity of sine wave in linear models? how to find the degree of similarity of directional movement of a sinewave using the Bayesian method? what is the measure for the directional movement of a time cycle how to find directional motion in a time series
