Maybe you should split up your questions in two posts?
Here is what I have tested on MutualInfo()
The simple syntax is: MutualInfo(TargetField,DriverField,Datatype)
You can add more input values after DataType but I'm not sure how to use those yet.
Datatype is not clear to me but on the session he talked about two discrete fields as Target and Driver, and then added 'dd' as data type, which makes me guess that continuous fields has a 'c' as datatype and discrete fields has 'd' so if your target is discrete and driver continuous (numeric) you enter 'dc' as data type. I tried this and it seems to work, but I am just guessing here...
The mutualinfo() will return a value between 0 and 1. The more related the Driver field is to the Target field, the closer it will be to 1. For instance if you enter the same field in Driver and Target you should get value = 1. and if there is no relation, for instance if you take orderNo as Driver and Churn as Target, you should be close to Zero.
Hope that helps.
