Extract coefficients from linear regressions Model

Matthias

Hi all,

I 've to extract the coefficients from a linear regressions Model. I want solve this with a little java script, following this topic
http://rapid-i.com/rapidforum/index.php/topic,2427.0.html
First I want to input the model with

IOObject ioobject = operator.getInput(IOObject.class);

However I don't know how to transform the IOObject into a LinearRegressionsModel so that I can use the getCoefficients() command.

Would be nice if someone has an idea

Greetings

Hi,
well actually casting would be a good idea. But if you aren't a Java freak, I would recommend using a simple operator for that: The coefficients are returned as weight Vector from the Linear Regression itself. So you can use it or transform it to a data set using Weights to Data. Then you can save it in any format you want. No coding needed at all...
