Linear regression vs logistic regression (image by author) Other regression models, like logistic regression, fit a curved line to the data. Linear regression models assume the data have a linear relationship, and thus fit a straight line to it. Essentially, regression techniques fit a line to the data, which allows you to estimate changes to the dependent variable (for example, price) as changes occur to the independent variables (for example, size). In Data science, regression analysis is primarily used in prediction and forecasting tasks. Building a linear regression model using scikit-learn.You can use the clickable menu to skip ahead to any section: By the end of this post, you’ll have an understanding of regression analysis, linear regression, and how to apply it. Then, we’ll build a more complex linear regression model using a few lines of Python code. First, we’ll build a simple linear regression model in Microsoft Excel. In this tutorial, we will briefly introduce regression analysis and look at linear regression examples. Even simple linear regression-one of the simplest algorithms-can be used to price homes. However, at its core, predicting a home’s value is simply a regression problem, since a home’s price is a continuous variable based on many independent variables like rooms, location, year built, and so on. In practice, predicting the price of homes months into the future is certainly a challenge-even for the most sophisticated algorithms. Although they could have spent more resources tuning their algorithm, they found the potential risks outweighed the benefits. Recently, AI and data science have been in the news, as real estate company Zillow Group shut down its home buying program that used predictive analytics to forecast the price of homes months into the future. Data science is a fascinating field that aims to solve challenging problems like autonomous vehicles and artificial intelligence (AI).
