How can I compare statistically two datasets in RapidMiner

edited November 2018 in Help

Hi,

I have two data sets. First measured values, second calculated using generate attributes. I would like to compare these data sets statistically. I prefer Leave-one-out Cross Validation [https://en.wikipedia.org/wiki/Cross-validation_(statistics)], but usage of Cross Validation is different in RapidMiner (Divide datasets as training and validation).

Any suggestion?

Data:

3 independent variable( > 200 examples)

1 dependent variable

1 predicted variable

    Hi @hapaydin,

     

    You have directly in RapidMiner access to the staistics of Runoff(M) and Runoff(Pre) in the Statistics

    panel of the Results and then compare their statistics :

    or you can use the Charts panels to represent your two datasets (Here an example using histograms) :

    If it's not enough, can you precise what you want .

     

    Regards,

    Hi again @hapaydin,

     

    To go further et to complete my last reply, you can explore the different operators

    of the Statistics Extension (to download and install from the Marketplace).

     

    I hope it will be helpful.
