Documentation
Definition
The trend dampening factor is a number that is multiplied by the trend value (growth rate) when the forecast value is calculated. This reduces the growth rate recursively for a long-term trend.
Use
Use a trend dampening factor if you want to hypothesize in you forecast that the past rate of growth will decrease in the future.
A value greater than 1 is also permitted as a trend dampening factor. This allows you to achieve the opposite effect.
Dependencies
Trend dampening is only taken into account with forecasting models that have a trend component. This includes linear regression and the exponential smoothing trend models (with or without seasonality).
Example
The sales quantity for a product has in the past always increased by 1000 a month. A trend dampening factor with the value 0.9 reduces the growth rate by 10% a month. That means that by the end of the following month, growth will be 0.9 * 1000 = 900, and at the end of the following month growth will be 0,9 * 900 = 810 etc.
