WebBefore jumping to the adjusted r-squared formula, we must understand what R2 is. In statistics, R2, also known as the coefficient of determination, is a tool that determines and assesses the variation in the dependent variable explained by an independent variable in a statistical model. WebFeb 3, 2024 · Your mathematical equation is a model based on various assumptions about the world. If your model doesn't match the data (I am careful not to say "data does not match the model"), then your model is not correct, although it pretty darn good in some respects. Answers and comments here have provided improved models. $\endgroup$ – WebVARIANCE: Variance, symbolized by s squared, equals 1 divided by the number of samples minus one, multiplied by the sum of each data point subtracted by the mean then squared.
