Identify decaying or growing sinusoidal graph
显示 更早的评论
I have a data set which either grows or decays over time.
The graphed data set looks like a sinusoidal graph with its amplitude either growing or decreasing over time.
What is the easiest way to identify if the overall trend is growing or decaying over time.
Thanks !
