log transform of dependent variable
I would like to perform a log transform of my dependent variable. I've tried to use the 'generate attributes' node, but I cannot figure out what to put in the 'function expression' portion of the node. I'm using RapidMiner 5.0 beta.

Alternatively, you can use AttributeConstruction to create a new attribute from an existing attribute "my_attribute" as in:
function descriptions: my_new_attribute
function expressions: my_attribute * my_atttribute
