      In the next section, the normal probability plot is discussed together with the associated Matlab program. In Section 2.3, the Matlab function concerning overfitting is discussed. 2.2 The Normal Probability Plot. 2.2.1 Background. One of the fundamental assumptions in standard linear regression is that of normal (Gaussian) errors.

      Multiple Linear Regression: The Equivalence of Least Squares & Covariance. In these notes we will address the linear model (1.0) Specifically, we will compare the least squares (LS) solution and the theoretical covariance solution for the model parameters. The method of LS typically is framed in relation to data; not random variables.
