SB_BinaryStats_mean_longstretch1 measures the longest successive period of above-average values.longstretch1 output from running SB_BinaryStats(x_z,'mean') in hctsa);SB_BinaryStats_diff_longstretch0 measures the longest successive period of successive decreases.longstretch0 output from running SB_BinaryStats(x_z,'diff') in hctsa).SB_BinaryStats_mean_longstretch1 computes the longest sequence of successive values in the time series that are greater than the mean. Algorithmically, this is achieved in two steps:1 and time-series values that are less than or equal to the mean are set to 0.1.SB_BinaryStats_diff_longstretch0 is similar to the above, but it calculates the longest sequence of successive steps in the time series that decrease. Algorithmically, this is achieved in two steps:1 if it is higher than the previous time point, and 0 if it is lower than the previous time point (starting from the second point in the time series, and thus yielding a sequence of length N-1, where N is the length of the original time series).0.
