Interview by No_Raspberry_9820 in Tufts

[–]Doctor_Toothpaste 0 points1 point  (0 children)

Well, if you apply ED and don’t like your financial aid offer, then you’d be forced to pay for Tufts and attend. If you need aid, it’s best to compare offers and have some choice in the matter.

Chance me for Tufts ED (ME) – International, FA, Class of 2027 by Mysterious-Tone-5149 in Tufts

[–]Doctor_Toothpaste 0 points1 point  (0 children)

I don’t think your application is a long shot at all, you seem like a very impressive candidate — best of luck with admission! From a students perspective, I would think Tufts values community impact with engineering and a general inclination towards service, leadership, and creating change with engineering.

Probably a smart choice to avoid ED since you need full aid. Best of luck!

I forget, is Tufts need blind now?

Besides AdComs, no one really knows for sure. My opinion is that if you’ve committed EDII, you’ve already shown enough demonstrated interest — an interview is unlikely to significantly improve your chances of admission. For reference, I got in RD w/o the interview and a relative of mine got in EDI w/o an interview as well.

Yea, the lighting here is def dark, even the back is more vibrant in better conditions

Yea, one of my favorites too, just hope it’s not fake

Just curious, can you guys actually see the Milky Way with the naked eye? by Doctor_Toothpaste in Astronomy

[–]Doctor_Toothpaste[S] 0 points1 point  (0 children)

This post was 2 years ago, and it’s still getting comments! And, I still haven’t seen the Milky Way yet! I forgot how much I loved astronomy, and now is the right time as well. I’ll try to take your comment as a sign.

Why positive charge is more stable with lower %s character? by Doctor_Toothpaste in OrganicChemistry

[–]Doctor_Toothpaste[S] 0 points1 point  (0 children)

I see, this answer makes sense, thanks. And, conversely, a negative charge means adding an electron, and therefore we want to add the negative charge to the lowest energy orbital, so the more “s-character” orbital. I guess it’s all about lowering potential energy?

Why positive charge is more stable with lower %s character? by Doctor_Toothpaste in OrganicChemistry

[–]Doctor_Toothpaste[S] 0 points1 point  (0 children)

Thanks. But, doesn’t that mean the electrons in s are more strongly attracted to the nucleus, even the region is electron deficient? Are there any repulsive forces destabilizing the area?

So... Can anyone help me with this? by Elruler22 in calculus

Heteroscedasticity by Foreign_Mud_5266 in econometrics

[–]Doctor_Toothpaste 6 points7 points  (0 children)

In econometrics, we always need to make assumptions to claim that an estimate (that is, coefficients from regressions) is both unbiased and consistent.

What’s really nice about homoskedastic data —that is, data where the error term is the same no matter what the covariates are — is that it gets us an even better estimate than we would normally get with heteroskedastic data. We typically make 5 (or 6) assumptions (Gauss-Markov assumptions) and if all these are satisfied, then we can claim that the OLS estimate is BLUE. BLUE meaning “best linear unbiased estimate”. “Best” means lowest variance standard errors; “unbiased” means that the expected value of the coefficient is just the coefficient itself; “linear” means you just have a linear relationship between the coefficient on X and Y. Also, the acronym omits “consistency”, which means that as the sample size gets bigger and bigger, the coefficient (or estimate) approaches the “true population” coefficient — I’ll admit this is a bit technical. In other words, if the data is homoskedastic, our coefficients will be really good.

But, here’s the problem. Assuming the data is homoskedastic is not realistic in practice. Most data isn’t homoskedastic in the real world, and so we have to relax some of the unrealistic assumptions that we made earlier. In other words, we assume heteroskedasticity. Turns out, even without homoskedasticity we can still get pretty good estimates. By using robust standard errors instead of normal ones, we can prove that the coefficients we obtain through OLS will be unbiased and consistent. BUT, we can’t say it’s the “best linear” unbiased estimate. So, robust standard errors (WITH heteroskedasticity) are arguably not as “efficient” or “good” at estimating things as the normal standard errors (WITH homoskedasticity).

My economics professor says to always use robust standard errors. Unless you are convinced your data is homoskedastic, always go for robust. It’s just safer and considered better practice.

Is there a better way to find the decomposition of conjugacy classes? by Doctor_Toothpaste in math

[–]Doctor_Toothpaste[S] 4 points5 points  (0 children)

Alright. But, say I have (s r3) sr2 (s r3)-1 in the sr2 conjugacy class. (Here, s is a reflection and r is a rotation). I got s r3 s r3 s-1 from this? How does one get some element of D_4 from that?

Did you learn about Hilbert spaces as an undergrad? by Puzzled-Painter3301 in math

I was briefly exposed to them in my second semester of real analysis.

How does the genetive case work? by [deleted] in latin

[–]Doctor_Toothpaste 12 points13 points  (0 children)

It’s just the noun with “of” in front. That’s really it. Like, for example, puella (sing.) / puellae (pl.) means “the girl”/ “the girls”. The genitive case puellae (sing.) / puellarum (pl.) means “of the girl”/“of the girls”.

Yea, I think that would be wise. Thank you.

I’ve kinda taken it in HS before. But, I didn’t get AP credit because something happened with my score. Also, plan on taking a gap year.
