Residual Autocorrelation Test
An F-test for serial autocorrelation in the residuals.
residual.corr.test(obj, lag.cor=1, alpha=0.95, dig1=5, dig2=3)
obj |
an object of class |
lag.cor |
the order of serial correlation to be tested for. Default is set to |
alpha |
significance level of test. Default is set to |
dig1 |
number of digits to display F-statistics and its critical values. |
dig2 |
number of digits to display p-values. |
It is the F-test of the familiar Lagrange Multiplier (LM) statistic (see Godfrey 1978a, 1978b), also known as the 'modified LM' statistic. The null hypothesis is that rho, the autoregressive parameter on the residuals, equals 0 indicating absence of serial autocorrelation. For higher order serial correlation, the null is that all rho's jointly are 0. The test is implemented as in Vanessa Smith's and Alessandra Galesi's ”GVAR toolbox 2.0 User Guide”, page 129.
Returns a list with the following objects
Fstat contains a list of length N with the associated F-statistic for each variable in each country.
resTest contains a matrix of size 2N times K+3, with the F-statistics for each country and each variable.
p.res contains a table which summarizes the output.
pL contains a list of length N with the associated p-values for each variable in each country.
