pyhctsa.operations.correlation.stick_angles(y)¶

Analysis of the line-of-sight angles between time series data pts.

Line-of-sight angles between time-series pts treat each time-series value as a stick protruding from an opaque baseline level. Statistics are returned on the raw time series, where sticks protrude from the zero-level, and the z-scored time series, where sticks protrude from the mean level of the time series.

Parameters:¶

y : array-like¶

The input time series

Returns:¶

A dictionary containing are returned on the obtained sequence of angles, theta, reflecting the maximum deviation a stick can rotate before hitting a stick representing another time point. Statistics include the mean and spread of theta, the different between positive and negative angles, measures of symmetry of the angles, stationarity, autocorrelation, and measures of the distribution of these stick angles.
