"Gamma Linear Regression - Do RapidMiner support this function?"

archique

Hi All,

I want to perform cross validation of linear regression, but in my case, my data do not support linear regression. I need to use Gamma Log Linear Regression. Could you please suggest which modelling function should I use? I have tried Linear Regression but when I compare the results using SPSS, it shows a big different.


Thanks,
Shahida

That I know there is no such operator in Rapidminer.

What would I do? I would do it in R. I'm thinking of

glm(count ~ x1+x2+x3, data=mydata, family=poisson())

If you still want to do a lot of computations in RapidMiner I would use "Execute R Script".

Here's a process (the dataset warpbreaks comes with R)

Read Warpbreaks Dataset






Split the data in a training and a test set



Train a Poisson model in R and return it as an R object



Apply the trained model on the test data
