State the properties of regression lines
WebRegression Model Assumptions. We make a few assumptions when we use linear regression to model the relationship between a response and a predictor. These assumptions are essentially conditions that should be met before we draw inferences regarding the model estimates or before we use a model to make a prediction.

WebSome of the properties of a regression coefficient are listed below: The regression coefficient is denoted by b. The regression coefficient of y on x can be represented as byx. The regression coefficient of x on y can be represented as bxy. If one of these regression coefficients is greater than 1, then the other will be less than 1. WebClassical Linear Regression In this section I will follow section 2.5 of Wooldridge very closely Our goal is to derive the mean and variance of the OLS estimator In doing so we need to make some assumptions about the population and the sample. This set of assumptions is often referred to as the Classical Linear Regression Model
