Overall, maximum likelihood is a very good approach to fit non-linear models. In this graduate text, we focus on one specific sector of the field, namely the spectral distribution of random Wigner matrix ensembles such as the Gaussian Unitary Ensembleas well as iid matrix ensembles. Regression analysis helps you to understand how the typical value of the dependent variable changes when one of the independent variables is adjusted and others are held fixed. Random matrix theory RMT has become quite a hot research area in applied mathematics over the past 25 years or so. The parallels we review are conjectural and still far from being understood, but the ideas have led to substantial progress in both areas. In order to fix this, you're going to fit a smaller model and use Lag1Lag2Lag3 as the predictors, thereby leaving out all other variables. Note that the constant 1 expands to the 3-by-3 matrix with all its elements equal to 1. Eliminate variables from an equation by using the variable's value from another equation. In practice, however, data is often perturbed by noise.
