Understanding the Coefficient of Determination (R squared)
The <strong>coefficient of determination</strong>, often denoted as <strong>r-squared (r²)</strong>, is a vital statistical measurement that reveals how well one variable can explain the variance of another. This concept is crucial in multiple fields such as economics, finance, and social sciences, providing key insights into relationships between data points. In this article, we will explore what the coefficient of determination is, how to interpret it, and methods for calculating it....
