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’...

Linear Regression in R R is a very powerful statistical tool. So let’s see how it can be performed in R and how its output values can be interpreted. Let’s prepare a dataset, to perform and understand regression in-depth now.

Part 1. What is Excel Linear Regression? 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 ...
line you’ll get. Here, the value of R Square represents an excellent fit as it is 0.94. It means that 94% variation in the dependent variable can be explained by the independent variable. In the case of multiple regression relationships, you have to keep attention to the Adjusted R ...
