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 ...

2D barcodes are newer and can hold more information than linear barcodes. 2D barcodes are square or rectangular and can be found on products, packaging, and labels. 2D barcodes can store a lot of information, so they are often used to store product information (such as nutrition facts) ...
In linear regression models, R-squared is a goodness-fit-measure. It considers the relationship strength between the model and the dependent variable. In this article, we will learn about R-squared (R2 ), r-squared value interpretation, limitations, how to interpret R squared in...
