## Classification Part 2: Logistic Regression with Test Data Set

Reading Time: 5 minutes In the previous post, we discussed the basics of Logistic Regression using the Smarket dataset from the ISLR package. Same as the previous post, this too is in line with free-to-access Introduction to Machine Learning course I am teaching on… Continue Reading

## Classification Part 1: Logistic Regression

Reading Time: 7 minutes Chapter 4 of the free Introduction to Machine Learning course I am teaching on IQmates introduces Classification methods. The videos touch on four methods: Logistic Regression, Linear Discriminant Analysis (LDA), Quadratic Discriminant Analysis (QDA) and k-Nearest Neighbours (kNN). In this post, we discuss… Continue Reading

## What is Linear Regression? Part 5: Dealing with Qualitative Predictors

Reading Time: 3 minutes We have so far been dealing with quantitative variables in this series discussing the basics of Linear Regression. There are many situations you will come across though where you will have to model using qualitative variables, for example when you… Continue Reading

## What is Linear Regression? Part 4: Non-linear Transformations of the Predictors

Reading Time: 3 minutes In the previous post, we discussed a way to introduce Interaction Terms to our Linear Model. The other previous posts talked about Simple Linear Regression and Multiple Linear Regression. Now we are ready to talk about situations where sometimes the… Continue Reading

## What is Linear Regression? Part 3: Interaction Terms

Reading Time: 2 minutes In the first part, we talked about the basics of Simple Linear Regression and in the second one, we discussed Multiple Linear Regression. In this post, we are going to quickly talk about Interaction Terms. As emphasised in the previous posts,… Continue Reading
