Hey sci,

do any of you know any R packages which can retrieve the most likely model from a set of datapoints?

What's your main source of fat?
I'm doing it with clarified butter mostly but I don't feel any more energetic.
Just less tired.

Looking for the shortest way to get the opposite of a number for example turn 4 into -4. I currently have x - (x * 2) but was wondering if there was a more efficient way to do so.

So I'm having some difficulties with my implementation of a finite element method.

I'm doing a log-log plot to check the convergence of the numerical solution, but it all appears wacko.

Basically, the 2-norm of the error ||u-u_h|| is increasing with finer meshes, but the 2-norm relative error ||u-u_h||/||u|| is decreasing.

Is my numerical method diverging? Is the 2-norm relative error increasing due to round-off errors? what's going on here.

Hi /sci/ I need your help in picking a module for next year. Here are the choices I've got:

Fluid Dynamics
Statistical Data Analysis
Physics of Galaxies

Now, I'm more interested in the first two rather than the last so I probably won't end up doing that. As for the first two, could someone explain how useful they might be later on? I suppose it's a question of what I want to do later on, but I'm one of those jackasses who aren't sure about that yet.

My guess is that Statistical Data Analysis would be more useful once I graduate because it could be applied to more jobs, whereas Fluid Dynamics is more significant to engineering purposes. What do you think?
