Implementing the new ppscore

[lucazav]

Recently a great addition in Data Exploration tools has been done: the predictive power score.
There is currently only the original implementation in Python here. dlookr could be the first R library to implement this innovating tool in a tidy way! I would not miss this opportunity!

Thank you so much, your recommend.

I read an interesting article about the predictive power score you introduced.
I agree very much. In the coming weekend, I will be busy fulfilling your proposal. Thank you very much.

Great! I suppose if you'll start implementing it parallelizing it using a multi-core approach, it'll be a win-win for dlookr!

Very late, but I implemented your suggestion with the following function in version 0.5.5.9000 of dlookr.:

• pps.data.frame()
• pps.target_df()
• summary.pps()
• plot.pps()

I am sorry that I kept my appointment late for various reasons.

I close the issue because I implemented that function.
