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.
A few days after I had a severe outbreak of canker sores I developed a swollen lymph node under my chin, right in the middle. I went to the dr's after 2 days and he put me on antibiotics. I am trying to figure out how serious this swollen lymph node may be. It is about the size of a pea. It is not as painful as it was.
