Hey,
Doesn't this give you a ridiculous Type 1 error? Maybe randomly select one
result and trust it.
Try bestglm or stepwise regression maybe.
Hope that's helpful,

be able to make inference from that
using parametric methods (once) which will fit the truth a bit better than a

man awk?
I've used awk for similar tasks (if I am reading the post correctly.) Google-Fu
should turn up some useful examples.
Also awk should be on your linux installation in some form or another.

Also with Linux you can add more swap memory(which I'm pretty sure R spills
into if it hasn't reached it's internal limits on 32 bit installations).
Windows pagefile is kind of obnoxious.

Rstudio and Rcmdr are very popular and for good reason, find a good book
while the latter is installing though.
IF you are using linux, rkward is fantastic to woRk with.

What type of singularity exactly, if you're working with counts is it a special
case? If using a Monte Carlo generation scheme, there are various workarounds
such as while(sum(vec)!=0) {sample} for example. More info on the error
circumstances would help.
Good luck!

I haven't actually tried this code (may contain clerical errors) but I hope
it gets you on the right track.
Good luck,

Best of luck, and sorry for the bad R jokes.

For random walk, there are entropy based tests (Robinson 1991), or you could
empirically test the hypothesis by generating random normal data with the same
mean and standard deviation and looking at the distribution of your quantiles.
You could make generic statements also about whether or not
