Every data scientist will likely have to perform linear regression tasks and predictive modeling processes at some point in their studies or career. For those of you looking to learn more about the topic or complete some sample assignments, this article will introduce open linear regression datasets you can download today. 2020-02-25 · Linear regression is a regression model that uses a straight line to describe the relationship between variables. It finds the line of best fit through your data by searching for the value of the regression coefficient(s) that minimizes the total error of the model. The aim of linear regression is to model a continuous variable Y as a mathematical function of one or more X variable (s), so that we can use this regression model to predict the Y when only the X is known. This mathematical equation can be generalized as follows: Y = β1 + β2X + ϵ where, β1 is the intercept and β2 is the slope. Natur & Kulturs Psykologilexikon.
