Nettet22. des. 2024 · In this article, we will discuss how to use statsmodels using Linear Regression in Python. Linear regression analysis is a statistical technique for predicting the value of one variable (dependent variable) based on the value of another (independent variable). The dependent variable is the variable that we want to predict or forecast. Nettet23. feb. 2024 · Data Structures & Algorithms in Python; Explore More Self-Paced Courses; Programming Languages.

The concept is to draw a line through all the plotted data points. The line is positioned in a way that it minimizes the distance to all of the data points. The distance is called "residuals" or "errors". The red dashed lines represents the distance from the data points to the drawn mathematical ...
