## Exponential Smoothing in Excel 2016 & 2013: Steps

When smoothing a data set with Excel, you may encounter the option to use either a simple or double exponential smoothing. What’s the difference?

A simple exponential smoothing algorithm uses a single smoothing constant, while a double exponential smoothing algorithm uses two smoothing constants. Triple exponential smoothing also uses three smoothing constants, but they are all different values.

Here’s a brief explanation of each:

• Single exponential smoothing: The smoothing constant is 1.0.
• Double exponential smoothing: The smoothing constants are 2.0 and 0.5, respectively.
• Triple exponential smoothing: The smoothing constants are 3.0, 2.0 and 1.0, respectively.

## Exponential smoothing formula

Exponential smoothing is a technique used in statistics to smooth data. The smoothing constant, k, is used to control the degree of smoothing. The simplest exponential smoothing model is the double exponential smoothing model, in which k = 2. The triple exponential smoothing model, in which k = 3, is more commonly used.

## If value of smoothing constant (alpha) is taken as 0, what is the meaning of it?

If the smoothing constant alpha is set to zero, then the algorithm is said to be in “linear” mode. In this mode, the output values will be proportional to the input values. When alpha is not set to zero, then the algorithm is said to be in “exponential” mode. In this mode, the output values will be proportional to the input values multiplied by a constant, called the “exponential smoothing constant.”

## Moving average and exponential smoothing method

Moving averages are a type of exponential smoothing. They are used to smooth data that has been collected over a period of time. The moving average is calculated by taking the average of a set of data points over a specific period of time. Exponential smoothing is a type of moving average. It is used to smooth data that has been collected over a period of time. The exponential smoothing algorithm calculates the smoothed value by using the following equation:

S = A*E(t) Where:

S is the smoothed value A is the original value at time t E(t) is the exponential function

## What effect does the value of the smoothing constant have on the weight given to the past forecast and the past observed value?

It gives a weight of α to the past observation and (1−α) to the past forecast. All the prediction of the time series will be based on the previous predicted value, and be a simple straight line using the first prediction. It will not have any predictive value.

## What value of the smoothing constant would make an exponential smoothing forecast the most reactive to recent demand changes?

A smoothing constant of . 1 will cause an exponential smoothing forecast to react more quickly to a sudden change than a smoothing constant value of . 3. Smaller smoothing constants result in less reactive forecast models.

## Why is exponential smoothing better than moving average?

For a given average age (i.e., amount of lag), the simple exponential smoothing (SES) forecast is somewhat superior to the simple moving average (SMA) forecast because it places relatively more weight on the most recent observation–i.e., it is slightly more “responsive” to changes occuring in the recent past.
