Add predict_proba method for LogisticRegression

[geosarr]

I'm submitting a

• bug report.
• improvement.
• feature request.

Current Behaviour:

Hi, the struct LogisticRegression does not have a method that directly returns the estimated probabilities.

Expected Behaviour:

It will be great to add a predict_proba method like (https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html), in order to account for unbalanced datasets.

Do you want to work on this issue?

yes.
