The Orthogonality Thesis; or, Arguing About Paperclips

WebThe proposed orthogonality test is then based on a test of the null hypothesis that Ły;∆x = 0, a parameter which is well deﬁned for both stationary and unit root nonstationary xt. To see the relationship between this parameter restriction and more common tests of orthogonality, note ﬁrst that yt orthogonal to Ix;t•1 implies Ły;∆x = 0. Orthogonal array testing is a black box testing technique that is a systematic, statistical way of software testing. It is used when the number of inputs to the system is relatively small, but too large to allow for exhaustive testing of every possible input to the systems. It is particularly effective in finding errors associated with faulty logic within computer software systems. Orthogonal arrays can be applied in user interface testing, system testing, regression testing, configuration tes…

WebTherefore the tests should be useful to the applied econometrician. 2. THEORY AND A TEST OF ERRORS IN VARIABLES The theory underlying the proposed specification tests rests on one fundamental idea. Under the (null) hypothesis of no misspecification, there will exist a consistent, asymptotically normal and asymptotically efficient estimator, 2 WebIt is fairly easy to conduct F F -tests in R. We can use the function linearHypothesis () contained in the package car. The output reveals that the F F -statistic for this joint hypothesis test is about 8.01 8.01 and the corresponding p p -value is 0.0004 0.0004. Thus, we can reject the null hypothesis that both coefficients are zero at any ...
