R-Single Exponential Smoothing Algorithms SAP Predictive Analysis

[Former Member]

This document gives the step by step procedure to use R-Single Exponential Smoothing Algorithm in SAP Predictive Analysis.

R-Single Exponential Smoothing:

The R-Single Exponential Smoothing algorithm enables you to smooth the source data by reducing noise and performing prediction for the time series data by using R library functions. Time series data is a sequence of observations over a period of time.

Let us walk through a simple example to work on the R-Single Exponential Smoothing

Step 1: The below Excel file have the OrderID and Sales Amount

Note:

When you use a time series model for analysis, the model does not consider data from the selected data source. Instead, it forecasts by considering data that was used while generating a model.

Step 2: Open the Predictive Analysis Tool.

Step 3: Go to FILE-> NEW-> Select the Data Source (here in this case select Excel)

Switch to “Predict” tab to set up the forecasting.

You can create a model by saving the state of a trained algorithm.

• In the application toolbar, choose the Designer button to switch to the designer perspective.
• Expand Time Series sub type.
• Drag the R-Single Exponential Smoothing algorithm onto the analysis editor.

  In the analysis editor, right-click the algorithm component and choose Properties

In the properties view, perform the following steps:

• Select Forecast as output mode, as you want to forecast the data.
• Select the Sales Amount column as the dependent column. The algorithm forecasts the data based on the Airline Passenger column.
• In the Period field, select Month (12).
• Enter 2011 as the start year.
• Enter 1 as a start period. As the period is Month (12), 1 implies first month of the year (January).
• Enter 12 for the number of periods to predict.
• Retain the default values for the advanced properties.

• The "Analyze the result" dialog is displayed.
• Select Yes to switch to visualization perspective.

To view the results click the Results and view them in Grid mode

Then Visualize your results using “Visualize” Tab

Hope it helps to use R-Single Exponential Smoothing Algorithm in SAP Predictive Analysis.
