Logistic Regression Example – Logistic Regression In R – Edureka Since here we need to predict whether she will get into the school or not, which is a classification problem, logistic regression would be ideal. Logistic Regression allows you to analyze a set of variables and predict a categorical outcome. So, based on her CGPA and the past data, you can use Logistic Regression to foresee the outcome. Let’s say that your little sister is trying to get into grad school, and you want to predict whether she’ll get admitted in her dream establishment. In order to understand why we use logistic regression, let’s consider a small scenario. Why And When Do We Use Logistic Regression? Regression – Logistic Regression In R – Edurekaįor such problems, you can make use of regression by studying the relationship between the dependent variable which is the stock price and the independent variable which is the time. Here you don’t have to label data into different classes, instead, you have to predict a final outcome like, let’s say you want to predict the price of a stock over a period of time. So, regression is basically a predictive analysis technique used to predict continuous variables. And this is exactly what a continuous variable is. The number of possibilities for height is limitless. Someone could be 165cms tall or they could be 165.02cms tall or they could be 165.022cms tall. A continuous variable is basically a variable that has an infinite number of possibilities.įor example, a person’s height. Regression analysis is a predictive technique used to predict a continuous quantity. Now that you have a brief understanding about Classification and Regression, let’s focus on Regression Analysis, which is the basic idea behind Logistic Regression. The number of possibilities for weight are limitless. Someone could weigh 180 pounds, they could weigh 180.10 pounds or they could weigh 180.1110 pounds. A continuous variable is basically a variable that has infinite number of possibilities. On the other hand Regression is used to predict a continuous quantity. You can also go through our content on Classification Algorithms to get a better understanding about the various Classification algorithms used in Machine Learning. One important point to note here is that the response variable for a classification problem is categorical in nature.Ĭlassification – Logistic Regression In R – Edureka For this kind of problems, where you have to assign the input data into different classes, you can make use of classification algorithms. Let’s say you want to classify your emails into 2 groups, spam and non-spam emails. they are used to classify a variable into one, of the two classes. Classification vs RegressionĬlassification problems are used to assign labels to an input variable, i.e. Now that you have an idea about the different types of machine learning, for this blog we’ll be focusing on Logistic regression which is a type of supervised machine learning algorithm.Ī supervised learning algorithm can be used to solve two types of problems:Ĭlassification & Regression – Logistic Regression In R – Edurekaīefore we move any further and discuss about Logistic Regression, let’s try to draw a line between Classification and Regression problems. This Edureka video on “What is Machine Learning” gives an introduction to Machine Learning and its various types. You can go through this video by our Machine learning experts to make yourself familiar with Machine Learning. It is also necessary to have a good understanding of Machine learning.

If you wish to learn more about the Types of Machine learning, you can check out our blog series on Machine Learning, it covers all the fundamental concepts of the various Machine learning algorithms and their use cases. There are 3 different approaches through which machines learn: Machine learning is the science of getting computers to act by feeding them data and letting them learn a few tricks on their own, without being explicitly programmed to do so.
