WebOct 9, 2024 · Teräsvirta’s test uses a statistic X 2 = T log ( SSE 1 / SSE 0) where SSE1 and SSE0 are the sum of squared residuals from a nonlinear and linear autoregression respectively. This is non-ergodic, so instead, we define it as 10 X 2 / T which will converge to a value indicating the extent of nonlinearity as T → ∞. port of tracyton https://shinestoreofficial.com
