Triple Brown

Brown's Triple Exponential Smoothing is implemented on data showing a quadratic trend over time. It works well for data that has a very steep growth or decline. The Brown's Triple Exponential Smoothing method attempts to create a linear equation by performing three simple exponential smoothing forecasts and then adjusting for the linear trend in the data.
