Time Series Prediction (Forecast into the Future)

Hi All,

 

I have spent the past few days learning the basics of RapidMiner and looking through the tutorials and existing posts. There are a lot of examples on time series prediction comparing existing data against predicted/forecasted data and scoring/ranking the two streams against each other.

 

I am yet to find any discussion on “predicting into the future” where there is no available data. Eg use only the past few years of daily data to predict the next 100 days. As always, my question relates to the stock price of a single company.

 

I have setup my design view to use an ANN as per below.

 

However I would like RapidMiner to predict the next 100 days etc into the future where I have no data as shown in the blue drawn line below. Has anyone done this before or would know of an example I can examine?

    Thanks @BalazsBarany I have completed that course. Have you ever seen an example of what I am trying to do? I am new to Machine Learning but but it interesting most people "test and train" but never actually try and predict into the future. 

    I do agree with you in that "stock prices depend on more factors than just the past values", hence my data set includes 21 fields with opening price being one field and the remaining 20 fields being other related data.

    Hi!

    I've seen presentations at conferences. People have been testing and comparing methods for predicting stock prices for decades. The results were underwhelming.

    In this field you're up against Wall Street companies with large rooms full of Harvard PhD holders. And even those companies don't have the magic model to beat the market.

    You can do a windowing on all 20 attributes and build your models with the windowed, "old enough" data. But don't expect a prediction horizon of 100 days with something as volatile as stock prices to be reliable.
