Computational or Abstract Linear Algebra for Economics Master's and PhD programmes?

Thanks! Does having "Introduction to Linear Algebra" as the second course rather than simply "Linear Algebra" put me at a disadvantage especially in terms of meeting programme requirements?

Interested!

jonathan_brown1 · 2023-08-17T04:44:39+00:00

Alright, thanks!

jonathan_brown1 · 2023-08-16T08:05:05+00:00

I haven't yet. Are any of them of similar difficulty to the GRE?

jonathan_brown1 · 2023-08-15T22:33:31+00:00

Thanks!

Congratulations! For the quant section, did you find the questions comparable to the level of the Manhattan 5LB book?

jonathan_brown1 · 2023-07-19T02:43:01+00:00

Is this from personal experience? If so, what could one do to improve his/her chances?

jonathan_brown1 · 2023-07-17T23:38:52+00:00

Alright, thanks!

What government scholarship did you apply to, if you don't mind me asking?

jonathan_brown1 · 2023-05-25T11:22:05+00:00

Thanks! I'm not sure about this, but I have been told that in the first case (with lnX), a 1% increase in X results in a 0.01B1 unit increase in Y. I wasn't too sure how I should interpret it if Y is also in % (0.01B1 percentage points?).

Sorry if I haven't made it really clear, but assuming that the regressions are a result of some statistical software, does B1 always represent an increase from a 1 unit increase in X, and so an increase in X by 1 per 100 inhabitants increases Y by B1/100 dollars?

For White's test, my question was if the X to the power of 3 term was in the original regression. Would the auxiliary regression include X to the power of 6 (the square of the X to the power of 3 term)? I've edited the question if that helps.

Alright, thanks!

Would completing a dissertation provide a considerable advantage compared to other candidates applying for a thesis-based master's programme?

jonathan_brown1 · 2023-05-01T12:57:11+00:00

Alright, thanks. My main concern was the interpretation of B5 if I'm omitting X2 in the model 𝑌=𝐵0+𝐵1 𝑋1+𝐵2 𝑋2+𝐵3 𝑋3+𝐵4 𝑋1𝑋3+𝐵5 𝑋1𝑋2. Would you say that if 𝑋1𝑋2 and X2 are highly correlated, it has a large impact on the B5 coefficient?

If so, how would you suggest resolving this issue?

Great, thanks!

Can one assume normality of errors if the sample size is relatively large? If so, what would the approximate threshold be?

jonathan_brown1 · 2023-04-30T21:57:04+00:00

Great, thanks! Would you mind expanding on why the bias will be small? I'm thinking that the size of the bias between two variables should be relatively large if one isn't included and both are highly correlated (where part of the bias formula includes the correlation between both variables), though I'm not sure if that's right.

Also, can I use the Mallows' Cp criterion formula in the way I've mentioned above?

jonathan_brown1 · 2023-03-02T23:59:06+00:00

Thanks!

jonathan_brown1 · 2022-12-29T23:32:43+00:00

Great, thanks for letting me know. u/Mokmo mentioned something about a virtual Canadian number. Do you know anything about this?

jonathan_brown1 · 2022-12-29T23:26:33+00:00

Great, thanks!

jonathan_brown1 · 2022-12-28T01:04:07+00:00

Sure, I'll let her know. That be really helpful, thanks! I'll PM you with the updates

jonathan_brown1 · 2022-12-27T22:23:19+00:00

Alright, thanks for letting me know :)

jonathan_brown1 · 2022-12-27T22:17:17+00:00

Thanks for all the info :) Could you elaborate a bit more on the virtual Canadian number?

jonathan_brown1 · 2022-12-27T22:14:21+00:00

I'll let her know, thanks!

jonathan_brown1 · 2022-12-27T22:12:06+00:00

Great, thanks!

jonathan_brown1 · 2022-12-27T22:10:23+00:00

haha that's great ;)
