=================================================
Plot model
=================================================

plots  model results 'y' (true labels) versus 'ypred' (predicted) from test data.

The plots is a great alternative to know where estimator/classifier fails to predict 
correctly the target. 
* Prepare our data - Use analysis data of Bagoue dataset since data 
is alread scaled and imputed
