[R-SIG-Finance] bds test

[alexios ghalanos]

1. You did not bother to mention the function or package, but I assume 
you mean the bds.test from the tseries package.

2. I would think that the examples in the documentation of bds.test are 
VERY clear as to what the output means.
The Null is that the series is i.i.d. (so p-value of zero obviously 
rejects this).

3. The BDS test is not nuisance-parameter free, so if you have obtained 
the standardized residuals from some GARCH model for example, then the 
asymptotic distribution of the test statistic will likely be affected by 
this (if you are using a standard GARCH then you can apply the 
correction of De Lima (1996) and pass the log standardized squared 
residuals).
