Learn linear regression, a statistical model that analyzes the relationship between variables. Follow our step-by-step guide to learn the lm() function in R.
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.
The error term,Eis in the formula because no prediction is fully accurate. Though someAdd-inscalculate errors off-screen, we mention it to clarify the analysis. However, theLinear Regressionformula becomesY=mX+C,if we ignore the error term. 4 Ways to Do Linear Regression in Excel Method 1 ...

R makes it very easy to fit a logistic regression model. The function to be called is glm() and the fitting process is not so different from the one used in linear regression. In this post, I am going to fit a binary logistic regression model and explain each step. The dataset We’...
Logistic regression is an estimation of Logit function. Logit function is simply a log of odds in favor of the event. This function creates a s-shaped curve with the probability estimate, which is very similar to the required step wise function. Here goes the first definition : ...
Linear regression is a powerful tool that can help us understand the relationship between variables and make predictions based on that relationship. For example, in finance, linear regression can be used to predict stock prices based on various economic indicators. In social sciences, it can be us...
