Rapidminer for finding statistics

I am a beginner in Rapidminer . While working on Rapidminer

  1. i didn't find how to calculate or get skewness and kurtosis of a attributes in an exampleset.
  2. I would like to know is there a way to get best fit line for a scatter plot graph
Solution

  • For skewness and kurtosis, you could either calculate it yourself using a combination of operators or you could use the R extension and use the moments package which contains these functions. I think I would use R.

    For the scatter plot question, you could use the Linear Regression operator to build a model that fits a straight line. You need to arrange for one of the attributes to be a label that is to be predicted by the other attribute.
