comment How to separate factors by dependent variables (arguments)?
Well, there technically aren't any terms at level -1 in the second case that do not contain x. Since the Head of the expression is a in this case it returns a[] indicating the missing terms. In the case of 2a[x] the head is Times. Depending on what you want you could add /.Head[expr][]:>Sequence[] which will remove the term.

comment Loops for Unit Root Test
@george2079 RandomVariate superseded RandomReal and RandomInteger for distributions in M8. For distributions that existed prior to that time it should still work but RandomVariate is certainly encouraged.

comment Implementation of smoothing splines function
@Ajasja oops, must have been copy/paste. I'm surprised no one caught that before now. I suspect the reason it was there in the first place was because my original code picked the knots automatically rather than using pre-set ones.

comment Statistics confusion
The main problem with using a hypothesis test for this is that they all become increasingly sensitive to even small deviations with sample size. You at least want one that looks at the bigger picture like Cramer Von Mises which integrates along the whole cdf.
