**Multiple linear regression –**Multiple Linear Regression is a supervised machine learning algorithm involving multiple data variables for analysis. It is used for predicting one dependent variable using various independent variables.

This module will drive you through all the concepts of Multiple Linear Regression used in Machine Learning.**Fitted regression lines –**A fitted regression line is a mathematical regression equation on a graph for your data. This model can be used to identify the relationship between a predictor variable (x-scale) and a response variable (y-scale) so that it can assess whether the model fits your data.**AIC, BIC, Model Fitting, Training and Test Data –**In this module, you will go through everything you need to know about several models such as AIC, BIC, Model Fitting, Training, and Test Data.

**Regression- Logistic Regression**

**Introduction to Logistic regression, interpretation, odds ratio – **Logistic Regression is one of the most popular ML algorithms, like Linear Regression. It is a simple classification algorithm to predict the categorical dependent variables with the assistance of independent variables.

This module will drive you through all the Logistic Regression concepts used in Machine Learning, interpret Machine Learning models, and find the odds ratio relationship.

Association rule mining is the data mining process of finding the rules that may govern associations and causal objects between sets of items.

Recommendation engines are a subclass of machine learning which generally deal with ranking or rating products / users. Loosely defined, a recommender system is a system which predicts ratings a user might give to a specific item. These predictions will then be ranked and returned back to the user.
