"Time Series Forecasting - Demo"

Hello all, I'm testing RapidMiner features and I need to build a simple Forecast model. I did a little research and I found a few videos and tutorials about that but all of them test the Performance or Accuracy of the models and never get a concrete result. Does anyone have a tutorial to build a sales forecast (Only having Date and Amount as Input) and Predict 1 month ahead?.

Thanks in advance.

PS: I'm sorry if I choose the wrong topic.

I quite like the Simafore blog. They have lots of practical examples on how to use RapidMiner to do various tasks in a business context:

Here is part one of their two part Time Series tutorial.

Hope that helps.

Thanks JEdward, actually I had already tried to adapt that tutorial to my sample data but I can't really predict anything. I set the Horizon value to 1 or 5 but It just shows my Data and not new Days with the amount.
Maybe I Misunderstood the Goals of this kind of tool but in Microsoft Mining I can get new predicted months/days based on my historical Data, is that possible?

Thanks again, have a nive day!

Okay. If I get you correctly, you have the values say:

Year	Population
1999	5m
2000	6m
2001	4.5m
2002	7m

And you want to predict the population in say... 2053. For that a very simple way is to generate a trend from the data you have and apply it to your unseen values.
Here's an simple example for demonstration with no model validation to test accuracy.
It uses the World Bank population data of Germany and it calculates based on the trend that the population will be 94,494,157 in 2053.
To get the World Bank operator install the Rapid Finance extension from the marketplace.

Is this closer to what you are after?

Brilliant! Thank you, It was really helpfull.

Those is for? because I need predict or forecast piping failures in a Distribution network of drinking water in a determinated place, I hace to put this programming code or i can build this model with the tools of RapidMiner?

Thanks you a lot of...
