lag | the number of lags. |
order | lag TODO |
type | the type of test statistic to be returned. Either "Chisq" for the Chi-squared test statistic or "F" for the F test statistic. |
fill | starting values for the lagged residuals in the auxiliary regression. By default 0 but can also be set to NA. |
