Further to the above, better results were found [24] compared to SADF when using a backward expanding window, which they introduced as backward SADF (BSADF). This performs the same supremum ADF test, but this time with a fixed ending point, r2, and backwards expanding window:
Although transaction fees don’t accrue to sellers, miners are permitted to prioritize fee-loaded transactions ahead of fee-free transactions when creating new blocks, even if the fee-free transactions came first in time.

Wavelet coherence plots as above highlight areas in the time-frequency space where the two series co-move. The warmer the colour, the higher the coherence (which can be interpreted as correlation) at that location in the time-frequency space; the colours used in this work range from dark blue (0, no coherence) to yellow (1, strong coherence). Statistically significant areas of coherence are surrounded by a thick black line.
