Recompose signal in time series componentes

Hello folks, I am using time series componentes to forecast an horizon of 4 weeks of income. The Remove Seasonality Componente outputs the removed seasonality column and used differencing to calculate it.

The ARIMA Predictor componente forecast the differenced value.

I need to convert the forecasted value to its original value (not differenced value).

Do you know any node that help me to do this job ?

Hello @hrecinos and welcome to the forum!

There are two components that do the job for you. The Restore Seasonality – KNIME Community Hub component and the Restore Trend – KNIME Community Hub.
We also have a blog post that describes the whole process (https://www.knime.com/blog/building-a-time-series-analysis-application).

Best regards
Jörg
