• Even if initial survival is poor in one year the effects are damped down by the fact that one year’s planting is not normally a discrete crop with respect to felling plans. (Burdon, 1977)
• In order to discern any patterns in the data, you'll frequently want to plot a smoothed curve that damps down these fluctuations. (Kabacoff, 2011)
