Is it possible that the model ******* sucks?

[Justin7]

Is it possible that the model ******* sucks?

You tell me. Have you reviewed its results, line move history, or methodology?

[durito]

Yes.

[Justin7]

Yes.

Educate me. How were the results in 2009-2011?

How did the line movements agree/disagree in that time period?

[durito]

I´m only talking about the methodology.

[Justin7]

I´m only talking about the methodology.

Excellent. Do continue, please. What are your thoughts on the methodology?

[JVP3122]

Is it possible that the model ******* sucks?

I'm not sure how. When creating a mathematical model, you determine equations which you would expect to accurately predict an outcome based on parameter inputs. I know it's a dumbed-down way to mention it, but essentially you're taking data, extrapolating a mathematical formula to describe said data, and use the formula to attempt to predict future results. That's exactly what the book says to do. Like he says in the book, the model won't work well in the long-term, but I'm using it as a beginning model from which I plan on expanding. Now, I don't have much experience with statistical models, but I am currently working on a mathematical model describing tissue growth in a porous medium, and the procedure is pretty similar, I would think.

[durito]

i will have to ask my daughter when shes done with it

[Justin7]

It's creepy how much she looks like my new daughter.

I trust you'll post her analysis when she articulates it to you, in whatever fashion she does?

[brumbies]

all babies look alike, duh

[MonkeyF0cker]

Yeah I know what you mean. The thing is, though, in modeling I feel like the basic idea is valid. You want to have an estimate for given stats to take place in a game and then calculate runs scored off of that. That's why I at least want to try and reproduce his model and then improve on it myself by determining which parameters to vary to improve the model. If I'm way off base I'd appreciate someone letting me know but I'm entering my fourth year in an applied math PhD program and in modeling in math the basic premise is similar. I'm not expecting his model to have any value as it is but it seems like a good starting point.

[JVP3122]

Don't believe me? I don't blame you, I don't know that I would if I were in your position. Try this on for size:

I'm doing my thesis proposal defense in the last week of August. The main focus of my research is tissue growth in a porous seeded scaffold in a perfusion bioreactor. The system we're analyzing is a coupled system of two equations, one defining the culture medium in the domain (steady-state), and the other describing the change in cell density (time-dependent). A group in Nottingham analyzed a model like this in a two-phase paper, in which they use the Navier-Stokes equations to build their model. Ours doesn't quite work in the same manner as we didn't start with the N-S equations, we just used standard conservation of mass principles. As such, we can use Darcy's Law to get an averaged fluid velocity in the domain, and then we don't have to explicitly calculate the shear stress in the pores. We've got a complete model in 1-D, on which will be the basis of my proposal, and right now I'm working on expanding it into two dimensions. I've gotten as far as solving -div(k grad p)=0 with k (the permeability) varying and thus the problem is not quite a standard Laplace equation. We can still use an Ax=b solver used for Laplace's equation to solve this, such as conjugate gradient or gmres. Next, I need to solve the equation for the culture medium in two dimensions using a 2-D interpolation like bilinear or bicubic interpolation for the x and y direction fluid velocity. How does that suit you?

Impressive. So, you're capable of applying first semester calculus to a live problem. They give PhD's out for that these days? Unreal.

But that's a good explanation as to why you can't formulate your own model and need someone to check your work upon COPYING someone else's.

Whatever.

Fluid dynamics in first semester calculus? Remember, I'm doing an applied math model, not a statistical one. You're actually trying to make me sound like an idiot for learning? How far did you go in school?

[MonkeyF0cker]

Fluid dynamics is simply applied mathematics and the math that you mentioned is nothing but first semester calculus.

I have a BS in electrical and computer engineering. Although, I'm not sure how that matters. Anything more is purely a waste of time and money if you ask me.

Oh, that's cute, you did engineering. Okay, then, I'll use small words and go step-by-step so you understand.

I asked you a rhetorical question, I didn't actually care what you did for your degree. I mentioned in my post that I was working on a PhD in applied math, and the reply that you submitted implied that you didn't believe me. Thus, I figured instead of just throwing mathematical terms that I can find on Wikipedia, and as I'm not about to tell you my name or send you my school website, I thought I'd talk about some of what I'm doing for research. Then you have the balls to say that it's first semester calculus? An engineering graduate has the stones to trivialize what I'm doing? Find me a first semester calculus course in which they work on solutions for the Navier-Stokes equations, do math modeling, work with tissue engineering, solve Laplace's equation (or even know what Laplace's equation is) in one and more dimensions using CG or GMRES, are able to solve coupled nonlinear integrodifferential equations in multiple dimensions, and work with bilinear and bicubic interpolation. If you can do that then I'll concede this little argument. While I agree our education doesn't matter in the betting world, I simply stated what I'm doing to imply that I'm capable of taking a basic model and working with it.

Don't waste time arguing with MonkeyFocker. At least at SBR, he seems very close-minded.

As a humorous FYI, I also have a degree in CPE/EE (but with some more math, poly sci and law mixed in).

[JVP3122]

I figured as much. I knew that posting that little comment might piss somebody off. I just had to throw something in there after he's going to try and trivialize what I'm working on.

You can give your "research" and equations (that you had no part in) all the fancy names you'd like, but it still comes down to the fact that the underlying mathematics is nothing but differentiation. I was doing derivatives in high school.

And it's quite comical how the entire point of this thread is to ask for help with COPYING a model, but you're certainly "capable of taking a basic model and working with it." Obviously.

Your education won't mean much of anything. If you ever get into the real world, you'll realize that. But you seem like someone who should teach since they certainly can't do.

[JVP3122]

Just a quick word as you still didn't understand my point. I'm not copying for the sake of copying and using. I'm trying to reproduce results from the basic model and improve on it. You saying that the underlying math is nothing but differentiation just proves the point that you have NO idea what you're talking about. I would pay to see you try to do some of this stuff. I've had real world jobs and chose to go and pursue a graduate degree, but it seems that your education was quite obviously a waste of time

[MonkeyF0cker]

Then again, maybe you did everything right, and Justin's model is pure garbage. Who knows. I know I wouldn't buy it to find out.

I just find it comical that someone who is pursuing a PhD in applied mathematics can't actually apply what they've learned on their own and would even need to buy a book like Justin's.

[JVP3122]

Well I obviously fell asleep during my baseball modeling class. They teach that in math PhD programs

I don't see anything but differentials in any of the equations you listed. But yeah, I SHOULD be familiar with them since most people perform fluid dynamics calculations as a daily routine. LOL.

The fact that you cannot derive a model on your own says everything.

[MonkeyF0cker]

Because baseball math isn't the same as regular math. Unreal.

In other words, you can't do something unless you're shown how to do it. Which means you should probably not waste your time with sports models.

Equations? I don't remember posting any. What the are you talking about? On top of that, why should I go through all of the trials and errors myself when the basic model has already been provided?

[JVP3122]

Yup all math is the same. Now I know why you think advanced math is first semester calc. I don't even know how to respond.

[pavyracer]

How do you get an engineering degree? Is it hard?

On top of what I wrote, all advanced applied math is solving PDEs. Because they contain derivatives does that mean it's calc 1?

[Kaabee]

LOL. An excuse to remove digs at your book. Huh, Justin? Unreal.

the digs are now in players talk so viewership just went up 10000000000%

[MonkeyF0cker]

It's basic level statistics, genius. How retarded are you?

[MonkeyF0cker]

Holy fukk. You posted NAMES OF EQUATIONS, you moron.

Trials and errors of a basic model? LOL.

Yeah. I have no idea why you'd want to create your own model when one is publicly available, works for a few weeks out of the season, and you're pursuing a PhD in applied mathematics. That was a joke. Right?

[JVP3122]

Oh my god. You looked up N-S and you still called it calc 1? This and you're saying I'm retarded? This combined with the fact that you can't seem to comprehend that I want to use it AS A STARTING POINT makes me lose interest in you. Now I know why Justin7 said to not bother with you; you're a complete and utter moron. I'm done with you, I'm going to bed

[Ra77er]

lmao even the math geeks are throwing down.....DJ and Tracer, AC bash and now this...

[durito]

Justin´s model requires nothing more than high school level math and statistics. And it fails even at that level.

[Extra Innings]

I live for this shit
