In this chapter, you will learn when to use linear regression, how to use it, how to check the assumptions of linear regression, how to predict the target variable in test dataset using trained model.
It’s even predicted it will still be used in the year 2118! In this linear regression tutorial, we will explore how to create a linear regression in R, looking at the steps you'll need to take with an example you can work through. To easily run all the example code in this ...
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 ...

A linear regression model helps in predicting the value of a dependent variable, and it can also help explain how accurate the prediction is. This is denoted by the R-squared and p-value values. The R-squared value indicates how much of the variation in the dependent variable can be explai...
Conclusion: The Power of Linear Regression Analysis in Excel Introduction to Linear Regression and its Importance Linear regression is one of the most commonly used statistical techniques that plays a crucial role in various fields such as finance, economics, physics, engineering, and social sciences....
In the SLOPE function, we selected cell range D5:D10 as known_ys, and C5:C10 as known_xs. The formula will return the slope of the regression line for these data points. Read More: How to Find the Slope of a Line in Excel Method 3 – Determine the Slope of a Regression Line Man...
