Logistic regression is a type of classification algorithm, that is used to classify or segregate or assign observations to a particular class or label. And this is used to predict the value of input by observing the previous set of output values. This algorithm is extensively used in machine learning and is a type of predictive analysis algorithm that is based on probability, used for classification problems.

If you wish to get certified than just knowing Data Science better, I would suggest you enroll in a good Data Science training. That would help you gain the required practical skills along with theoretical knowledge to help you move forward in the career with the right skillsets.
