## Types of FORECAST.ETS in Excel

Differentiate FORECAST.ETS in Excel with Simple Exponential Smoothing (SES). It’s perfect for no-trend, no-seasonality time series. Use Holt’s Linear Trend Model (Holt) when there’s a trend but no seasonality. For heavily trended data, use Damped trend exponential smoothing (damped).

### Simple Exponential Smoothing (SES)

Using a basic statistical approach to determine trends and patterns, Simple Exponential Smoothing (SES) is an effective forecasting method. By using a weighted average approach, SES generates forecasts that quickly respond to changes in data and are widely used in financial analysis and inventory management. With the help of smoothing parameter alpha, the method assigns more weight to recent observations while disregarding historic ones. The resulting forecasts vary depending on the alpha value assigned.

An important feature of SES is that it can only be used for time-series data with no significant trend or seasonality. For datasets with trends or seasonality, alternative methods should be employed, such as Holt-Winters Exponential Smoothing (HWES) or ARIMA models.

Pro Tip: Avoid overfitting by using the method on segmented datasets rather than applying it across all available data points.

Get ready to Holt on tight, because this trend model is about to take us on a linear ride.

### Holt’s Linear Trend Model (Holt)

The Holt’s Linear Trend Model, commonly referred to as Holt, is a type of FORECAST.ETS in Excel used to forecast time series data with a linear trend and level that changes over time. It is particularly useful for data exhibiting trends that occur at irregular intervals.

 Input Output Time series data with a linear trend Forecasted values with changing level and trend α – smoothing constant for level β – smoothing constant for trend xt Fitted value at time t

Compared to other types of FORECAST.ETS, Holt allows for more flexibility in capturing the changing nature of the time series data. While it can accurately predict future values, it should be used cautiously if there are no underlying patterns or factors driving the observed trends.

A company used Holt to predict their quarterly sales revenue for the upcoming year based on previous years’ data. Despite accurately forecasting growth during the initial months, they eventually realized that unforeseen circumstances such as a new competitor entering the market had created substantial changes in their sales pattern, leading to incorrect predictions by Holt.

If you’re looking for a smoothing technique with less bounce than a trampoline, try damped trend exponential smoothing in Excel.

### Damped trend exponential smoothing (damped)

This smoothing technique, involving a damped trend, is a type of exponential smoothing used to forecast time series data. It places less emphasis on older observations and more on recent ones, while also dampening the effects of any underlying trends.

The damped trend exponential smoothing method involves calculating an exponentially-weighted moving average of past data points while considering historical trends and adjustments for overfitting. This method reduces the variance in the forecast and considers both the level and trend components in predicting future values.

Notably, this technique assigns less significance to older data as they become farther removed in time, decreasing their influence on future predictions. It also adds a “damping factor” to reduce the impact of long-term trends that may no longer be relevant.

To achieve optimal results using this method, it is recommended to consider alternative techniques such as Croston’s method or ARIMA models, based on the specific characteristics of the data being analyzed. Additionally, incorporating non-linear transformations or kernel-based methods can improve forecasting accuracy with complex datasets.
