%description
Innovative Trend Analysis is a graphical method to examine the trends in
time series data. Sequential Mann-Kendall test uses the intersection of
prograde and retrograde series to indicate the possible change point in
time series data. Distribution free cumulative sum charts indicate
location and significance of the change point in time series. Zekai, S.
