In matrix terms, the null hypothesis is specied by H o : C = 0, whereC = 0 0 0 1 0 0 0 0 0 ;1 0 Note how the elements of the C matrix correspond to the coecients of the linear constraintwhich corresponds to the null hypothesis.Store the above matrixas1rowinto le glt3.mat, and execute the script for the previousexample, except replace the -glt command line with:;glt 1 glt3:mat; glt label 1 "Difference"The output is the same as for Example 1.4.3.5, but with the additional GLT output:General Linear Test: DifferenceLC[0] = -0.2026R^2 = 0.0045 F[1,7] = 0.0315 p-value = 8.6417e-01Verify that LC[0] = h R [1] ; h E [1].Example 1.4.4.4 Comparison of two dierent impulse response functionsTo test whether the response to stimulus r(t) and to stimulus e(t) are equal at all timelags, i.e., to testThe null hypothesis can also be written:H o : h R [i] =h E [i] i =0 1 2vs. H a : not all h R [i] =h E [i]:H o :8
