Error - 'argument of length 0'

[Former Member]

Hi

I am using Predictive Analysis 1.0.10. I can run the clustering algorithm (R-K-Means) successfully so I assume that I am set up and configured correctly, but I get an error when I run the Decision Trees algorithm (R-CNR Tree):

     "Error in 1:nrow(object$splits) : argument of length 0

I have tried various permutations of fields and settings.

Any idea what the problem might be?

Thanks

Al.

Hi Al,

Do you get this error regardless of data sources used in PA?

I have 1.0.10 and R-CNR works fine here.

Try the following.

Check the logs for further information. The logs are by default are stored in %TEMP%\sapvi\logs folder.

Hello,

Im having the same problem, could someone please help. I have noticed that it only starts working if my 1s are in equal proportion with 0s. On my original data, i just have 8% as 1s, any ideas, please its urgent.

Looking forward to hearing from you.

Hi Sukruth,

thanks for for reaching out.

A Way to increase your predictions is to oversample of boost your 1s.

You find this approach described here:
