The test is a Wald test on the augmented model, which replaces the original as the "current model" for the purposes of, for example, retrieving the residuals as option (available only for the models estimated via OLS), an LM test is performed.
In many real-world simulations, the sparsity pattern changes little or not at all.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. Each of these plural constructors accepts an integer or several strings.CHOLMOD is a set of routines for factorizing sparse symmetric positive definite matrices of the form A or AAT, updating/downdating a sparse Cholesky factorization, solving linear systems, updating/downdating the solution to the triangular system Lx = b, and many other sparse matrix functions for both symmetric and unsymmetric matrices.Its supernodal Cholesky factorization relies on LAPACK and the Level-3 BLAS, and obtains a substantial fraction of the peak performance of the BLAS. CHOLMOD is written in ANSI/ISO C, with both C and MATLABTMinterfaces.
