A transform function to the scorecard object

Adding a .transform function to the Scorecard class

I was working on stress-testing a model we built using Optbinning a while ago. I needed to induce stress to each of the raw features and see the response on the scorecard points. It turned out that it was essential to have a transform similar to BinnintProcess.transform(X, metric="woe"), but this time with metric = "points". The stress induced on the scores was easy to understand when one changes one feature and leaves the other unchanged. I implemented it and was satisfied with it. To confirm, the sum of the scores plus the intercept gives the same value as the scores from the .score() method.

Would you be interested in adding this method to the package? It is straightforward, so I can implement it and do a PR.

Hi @jnsofini.
Thanks for your suggestion. Then, it would be:

• scorecard.binning_process_.transform(metric="woe")
• scorecard.transform(metric="point")

Since the scorecard transform is limited to points, the kwargs might not be necessary, i.e, scorecard.transform().
