About Multiple Regression Model
Hey there
I am about to get crazy.
I am trying to set up multiple linear regression, but at the end of the operations, the variables and their coefficients do not appear in the result section. It's just the slope result. So, I can't set up the regression equation.
I am following the path as retrieve fiile-set role (fix the variables)-cross validation-linear regression-apply model-performance regression
Please help.

When you run your model, you should see "LinearRegression" tab among those tabs you will get at the results window. Click on it, and to its left, you should see three icons, 'Data', 'Description' and 'Annotations'. The variables with their coefficients are at the 'Description' icon.
Note that RapidMiner will only give you those that are important. Check that with your p-values and the code it attaches to each variable.
Best regards.
Thank you for your comment. I really appreciate it.
I have 6 variables affecting my dependent variable in my data set. When I chose particular one of them in set operator, I dont get any coefficient neither in the linear regression tab nor in description icon. Strangely enough, I get coefficients if I chose one of the remaining five. Thats the problem I cannot sort out. May I send you my data list through mail if possible?
Feel free to attach your data and model here. There are many others who are willing to add more aid.
You might be looking at the 'Performance' tab instead, thus, seeing only those correlation and others. Or maybe, you didn't connect the "model" node of your 'apply model' parameter to the output.
Please check well.

The data set is below.
My dependent value is the energy produced in the turbine.
Other 5 are independent variables.
As I said, when I take the energy produced in the turbine as dependent variable, no coefficient appears. However, when I take one of the remaining five, no problem occurs.
Also, I discovered something called generalized linear regression. I get coefficient by using that one. Is it the same as linear regression? Because, the prediction values seem pretty close to actual ones.
And one more thing:) Please show me the way to write the file in excel by using write excel operator. I couldnt figure out how to connect and what to connect.
I know, I am being a bit too much, but very curious. Sorry about that.
Please check here [https://community.rapidminer.com/discussion/37047] on how to attach data and a model. It will make it easy for people to access.
For writing an excel file, you can find video tutorials on that [https://academy.rapidminer.com/courses/data-loading-via-a-process] or even on YouTube.
