How to perform Chi-Square Test in RapidMiner Studio?

Hi Expert,

 

As I need to perform chi-square test for independence for categorical variables, may I know how to apply by rapidminer studio?

 

Walked through the operator "AttributeWeights (Weight by Chi Squared Statistic)" that maybe relevant, but the result of this operator only provides the result of weight by attribute. How can we interpret the result from this operator?

 

Thanks,

Derek

Hi, you could check out the statistics extension from our Partner, Old World Computing: https://oldworldcomputing.com/products/statistics-extension-for-rapidminer

 

It has much more Statistics functions, including Chi-Square Test.

 

Also, you can review this thread: http://community.rapidminer.com/t5/Original-Rapid-I-Forum/chi-squared-statistics-returned-by-RapidMi...

I also highly recommend the Statistics extension--if you have any questions about it, you can ask @land directly.  But it has many other options including Spearman correlations, Mann-Whitney, K-S, and of course Chi-Square as previously mentioned.   Very useful to be able to incorporate these directly within RapidMiner in my experience.
