Nettet20. aug. 2024 · This measures the strength of the linear correlation between two data sets, so Desmos will display it in the special case that your model is linear and contains both slope and intercept parameters (e.g., \(y_1 \sim mx_1 + b\)). The coefficient of determination (\(R^{2}\)). This measures your regression model’s “goodness of fit.”

NettetY = Xβ + e. Where: Y is a vector containing all the values from the dependent variables. X is a matrix where each column is all of the values for a given independent variable. e is a vector of residuals.
