Nettet11. apr. 2024 · Linear regression is a method for predicting y from x. In our case, y is the dependent variable, and x is the independent variable. We want to predict the value of y for a given value of x. Now, if the data were perfectly linear, we could simply calculate the slope intercept form of the line in terms y = mx+ b. NettetIf you are familiar with linear algebra, the idea it so say that: Y = 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.
