The TS Forecast Factory tool provides forecasts from groups of either ARIMA or ETS models 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 programming language. Go to Options > Download Predictive Tools to install R and the packages used by the R Tool.
Input M: An Alteryx stream of ARIMA or ETS model objects generated by the TS Model Factory tool. Generally, you'll use the O output from the TS Model Factory tool as the M input. However, because the TS Model Factory tool produces some models using covariates and others without covariates, Alteryx recommends that you filter these models: use one TS Forecast Factory tool on the models with covariates and one on the models without them.
Input C: The future values for covariate fields. (Optional. Use this input only if the original models used covariates.) The number of rows in this input must equal the product of the number of groups with covariates and the number of periods being forecast.
