In the next section we present empirical comparisons for several linear regression estimation using three representative loss functions: squared loss, least-modulus and -insensitive loss with selection of given by (17). Our goal is to investigate the effect of a loss function on the prediction accuracy of linear regression with finite samples.

Under simple linear regression with normal errors, we have: Under least squares (and maximum likelihood) to estimate the model parameter, we obtain as the estimate of 0, and have as the fitted value for each observation.

There is a meaningful linear relationship between the two variables. Step III & IV: Estimates and evaluation: We estimate the model using least square method. The computation from the minitab is as follows: The regression equation is. Weight = 123 - 5.57 Day

Simple linear regression uses the ordinary least squares procedure. As briefly discussed in the previous chapter, the objective is to minimize the sum of the squared residual, . The idea of residuals is developed in the previous chapter; however, a brief review of this concept is presented here.

Multiple Regression Case. In the previous reading assignment the ordinary least squares (OLS) estimator for the simple linear regression case, only one independent variable (only one x), was derived. The procedure relied on combining calculus and algebra to minimize of the sum of squared deviations.

Summary: Basic Concepts of Linear Regression Analysis (one independent variable) ... Write the equation for using the least square method. Examine R2 and sLF. What do they tell you about the relationship? R2 is the coefficient of determination. It is the percent of raw variation in Y accounted for by using the fitted equation.
