Tool: Model Comparison

is there any guild about the tool model comparison?

when I try to use this tool I get the following information:

Error: Model Comparison (28): Tool #3: Error in match.fun(FUN) : object 'getXVars' not found

Also, in the model comparison configuration page: it asks you to input the positive class in target variable, my target is string was defined as 1 means bad and 0 means good. What should I input for this question?

I hope it could have more documentation about the predictive tools. Thank you so much.

Hi,

I had the same problem, this was my solution :

Step 1 : Go to R to download the ROCR package :

Step 2 : go to the directory C:\Users\my_name\AppData\Local\Temp\RtmpOoEUKw\downloaded_packages

Step 3 : unzip the file ROCR_1.0.7.zip

Step 4 : copy the folder generated in step 3

Step 5: paste the folder here : C:\Program Files\Alteryx\R-3.2.3\library

Step 6 : run Alteryx.

Hope this will help you.

Best regards,

Gilles

Hi @Inactive User, first thank you for downloading and using this tool. My first question for you: are you getting this error also when you run the Model Comparison Sample? If it's the case, what is your current Alteryx version? I've experienced errors with older version Alteryx when running with Model Comparison, but it should work with the latest version of Alteryx.

I'm happy to take a look at your workflow if this is not a Alteryx version issue.

To answer your second question, I would suggest put "1" in the box without quotes. However, you are probably the best person to answer this question -- what do you consider as your "positive" class? If you application is that you are studying what parts of a machine are "bad", then usually "bad" ("1") should be the positive class. Another example: if you are studying which patients have cancer, then patitents who have cancers are usually considered as "positive"

Hi@KuoL , thank you for the reply.

When I submitted the question, I use 10.1. I don't know if it has the error to run the Sample.

Right now, I have updated to 10.6, when I run the sample, I get the following error information. I have already installed the R predictive packages. But it seems like I need to install the package manually.
