Exact critical values are difficult to obtain Durbin–Watson Bounds. T K dL dU The following table provides the critical values for the Durbin-Watson Test for a given sample size (n), number of independent variables (k), and alpha level If we choose α =, then Tablegives the critical values correspond-ing to n =and one regressor as dL = and dU = ∵ d = Durbin-Watson Statistic Probability in Table AModels with an intercept (from Savin and White) Durbin-Watson StatisticPer Cent Significance Points of dL and dU k’*=1 *k’ is the number of regressors excluding the intercept k’=2 k’=3 k’=4 k’=5 k’=6 k’=7 k’=8 k’=9 k’=ndL dUdL dUdL dUdL dUdL dUdL dUdL dUdL dUdL dUdL dU The DW test statistic varies fromto 4, with values betweenandindicating positive autocorrelation,indicating zero autocorrelation, and values betweenandindicating negative autocorrelation. table durbin watson for you , · See Johnston and DiNardo (, Chapter) for a thorough discussion on the Durbin-Watson test and a table of the significance points of the statistic. T. W. Anderson, Department of Economics and Department of Statistics, Stanford University. The model is y = Xβ +u, where y is an n-vector of dependent variables, X is a matrix of n × k independent variables, and u is a Durbin Watson test statistics (no \ autocorrelation) To evaluate the performance models for predictions, performance indicators are used [9]. A regressor xis s;u t where \ (e_ {t}=y_ {t}-\hat {y}_ {t}\) are the residuals from the ordinary least squares fit. There are three main limitations of the DW test as a test for serial correlationThe Durbin -Watson statistic ranges in value fromtoA value nearindicates non-autocorre lation; a value towardindicates positive autocorrelation; a value towardindicates negative autocorrelation.

T= to, K=2 to K includes intercept. Find, read and cite all the research you need on The Durbin–Watson test, however, requires tto be distributed N(0;˙2) for the statistic to have an exact distribution. Also, the Durbin–Watson test can be applied only when the regressors are strictly exogenous. , · A with an intercept (from Savin and White) Durbin-Watson StatisticPer Cent Significance Points of dL and dU k’*=k’=2 1, · PDF The paper describes one way to demonstrate the Durbin–Watson statistic to a large class of students.
