In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', 'covariates', 'explanatory variables' or ...

- How is the error calculated in a linear regression model?Linear regression most often uses mean-square error (MSE) to calculate the error of the model. MSE is calculated by: measuring the distance of the...
Learn how to use regression analysis to describe the relationship between independent and dependent variables, predict the mean value of the dependent variable, and check the assumptions of the model. This tutorial covers many facets of regression analysis, such as choosing the right type, specifying the model, interpreting the results, making predictions, and checking the assumptions. It also provides examples of different types of regression analyses using real-world data.
In statistics, linear regression is a statistical model which estimates the linear relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables).
Nov 4, 2015 · Learn the basics of regression analysis, a type of data analysis that helps you understand how a variable changes over time or across different groups. Find out how to interpret the results, the types of models, and the applications of regression analysis in various fields.
Linear regression is a process of drawing a line through data in a scatter plot. The line summarizes the data, which is useful when making predictions.
