, Definition 10 of 49
A trend pattern exists if the time series plot shows gradual shifts or movements to relatively
higher or lower values over a longer period of time.
Trend pattern
Cyclical pattern
Horizontal pattern
Seasonal pattern
Definition 11 of 49
A time series whose statistical properties are independent of time. For a stationary time series
the process generating the data has a constant mean and the variability of the time series is
constant over time.

Definition 12 of 49
A cyclical pattern exists if the time series plot shows an alternating sequence of points below
and above the trend line lasting more than one year.
