Due to the summation (integration) from to, linear trends in the mean of the profile represent constant trends in the initial sequence, and DFA1 only removes such constant trends (steps) in the. In general DFA of order removes (polynomial) trends of order. For linear trends in the mean of at least DFA2 is needed.
