In this scenario, the real estate agent should use a simple linear regression model to analyze the relationship between these two variables because the predictor variable (square footage) is continuous. The design matrix is defined to be a matrix such that (the j column of the i row of ) represents the value of the j variable associated with the i object. A regression model may be represented via matrix multiplication as where X is the design matrix, is a vector of the model's coefficients (one for each variable), is a vector of random errors with mean zero, and y is the vector of predicted outputs for each object.
