Web28 de mar. de 2024 · Em desenvolvimento de software a definição de ortogonalidade é exatamente a mesma que a utilizada no âmbito matemático. Na álgebra, diz-se ortogonais quando duas grandezas possuem o produto escalar (ou interno) igual a zero, x ⋅ y = 0. O cálculo do produto escalar pode ser resumido à x ⋅ y = x y cosθ, sendo θ o menor ângulo … 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.
