• [PDF File]1 Simple Linear Regression I – Least Squares Estimation

  https://info.5y1.org/linear-regression-in-excel-formula_1_3f9dde.html

  One limitation of linear regression is that we must restrict our interpretation of the model to the range of values of the predictor variables that we observe in our data. We cannot assume this linear relation continues outside the range of our sample data. We often refer to β0 +β1x as the systematic component of y and ε as the random ...
