In Excel, Linear Regression is a statistical tool and a built-in function used to find the best-fitting straight line that describes the linear relationship between two or more variables. It is commonly employed for predictive modeling and analyzing the relationship between a dependent variable and ...
linear relationship between two variables, we can make inferences, predictions, and estimate the values of the dependent variable when we have the values of the independent variable. Excel, the popular spreadsheet program by Microsoft, provides a simple yet powerful set of tools to perform linear ...
Introduction to Linear Regression in Excel Linear regression is a statistical technique/method used to study the relationship between two continuous quantitative variables. In linear regression, we use independent variables to predict the value of a dependent variable.If there is only one independent var...
