As of now, we have seen how to implement the logistic regression on our own. Got the accuracy of 94.45. Let’s see the results from the popular Machine Learning (ML) Python library. 7. Test with Scikit learn logistic regression. Here, we are going to train the logistic regression from the in-build Python library to check the results.
Logistic Regression (aka logit, MaxEnt) classifier. In the multiclass case, the training algorithm uses the one-vs-rest (OvR) scheme if the 'multi_class' option is set to

To run a logistic regression on this data, we would have to convert all non-numeric features into numeric ones. There are two popular ways to do this: label encoding and one hot encoding. For label encoding, a different number is assigned to each unique value in the feature column. I was under the belief that scaling of features should not affect the result of logistic regression.

We’ll see that scikit-learn allows us to easily tune the model to optimize predictive power. Statsmodels will provide a summary of statistical measures which will be very familiar to those who’ve used SAS or R.
