# TS Forecast Tool

** One Tool Example**

TS Forecast has a One Tool Example. Visit Sample Workflows to learn how to access this and many other examples directly in Alteryx Designer.

The TS Forecast tool provides forecasts from a model created with either the ARIMA tool or ETS tool for a user-specified number of future periods. In addition, upper and lower confidence interval bounds are provided for two different (user-specified) percentage confidence levels. For each confidence level, the expected probability that the true value will fall within the provided bounds corresponds to the confidence level percentage.

This tool uses the R tool. Go to **Options** > **Download Predictive Tools** and sign in to the Alteryx Downloads and Licenses portal to install R and the packages used by the R tool. Visit Download and Use Predictive Tools.

## Connect an Input

The TS Forecast tool requires a data stream that is the output stream from either an ARIMA or ETS tool.

## Configure the Tool

### Configuration Tab

Use the **Configuration** tab to set the controls for the time series forecast.

**The field name for the point forecast**: The field name for the point forecasts in the output data stream. This name is also used as a prefix to the confidence bounds.**The percentage value of the larger confidence interval**: Set a value between 1 to 99. Commonly used values for this range are 95 or 99 percent.**The percentage value of the smaller confidence interval**: Set a value between 1 to 99. Commonly used values for this range are 80 or 90 percent.**The number of periods into the future to forecast**: Both the point forecasts and the confidence bounds will be available for the specified number of future periods.

### Graphic Options Tab

Use the **Graphics Options** tab to set the controls for the output plot.

**Plot size**: Select inches or centimeters for the size of the graph.**Graph resolution**: Select the resolution of the graph in dots per inch:**1x (96 dpi)**,**2x (192 dpi)**, or**3x (288 dpi)**.Lower resolution creates a smaller file and is best for viewing on a monitor.

Higher resolution creates a larger file with better print quality.

**Base font size (points)**: Select the size of the font in the graph.

## View the Output

Connect a Browse tool to each output anchor to view results.

**O**anchor: Contains a data stream of the forecast values and confidence bounds.**R**anchor: Consists of the report snippets of a table with the forecast values and confidence bounds and a forecast plot that shows both the historical values of the time series and forecast values with error bounds.**I**anchor: An interactive HTML dashboard consisting of plots and metrics. Select different graphical elements to interact with the visualizations to reveal more information, values, metrics, and analytics.
