求助 数学课选课 和 专业区别问题

李纸UID: 3611673

lz目前大三，美弱本，最初acc专业，大二时double了开设同在商院的business econ专业。
现在想申经济的master但是发现数学课差很多
目前已经上过的和排课计划上的数学课只有：
Calculus 1,2,3 和 Introduction To Linear Algebra
由于时间有限（已经晚了orz），受前置课约束应该补不上real analysis的课程了，请问lz目前的这些数学课能不能满足eco master 的申请要求，还有哪些必须要上或者强烈推荐的数学课？

－－－－－另一个问题的分界线——————
lz本打算一直安于acc专业，现在考虑申研时才决定推翻以前的计划。可是我不清楚business econ 到底和SBS里的正常eco专业差别多大？以下是lz上过的和准备上的eco课程：
微观宏观原理，中级微观宏观
Senior Seminar In Economics，Introduction To Econometrics，
The Political Economy Of Energy，International Economic Development，
Money And Banking，International Economics，和一些acc和其他商科专业的课程，应该和申请eco的master没太大关系，就不列出来了，求知道的热心人指点

楼主 为什么不好好学Acct 要换Econ?:L

you need intro to probability (calculus based), and also intro statistics.

Real analysis is strongly recommended if you want a academics master in economics.

and then a few more senior level math/stat courses are always useful, e.g. time series, optimization, stochastic process, differential equation, and etc...

I guess most likely one feels that accounting is too boring, and economics sounds more interesting, given that one don't know
1. how difficult/mathematical graduate level economics is
2. how much have to be studied before things are really applicable
2. how much more difficult it is to seek a job without a useful technical skills.

Thank you for your response.
I missed to list Introduction To Business Statistics that I have taken, is that equivalent to intro statistics?
Will Introduction To Analysis make big help in application? I want to apply for academics master but I cannot finish all pre courses of Real Analysis before graduating.

Business statistics 太浅了 不能替代Stat department 的上一年的Prob&Stat sequence
不知道你说的Intro Analysis 和 Real analysis 分别是什么层次的
一般Intro Analysis是指本科高阶的Baby Rudin 层次的课 本科学这个不错了 不过老美经常把这课叫成real analysis

因为喜欢经济，有phd的dream（但觉得对于现在的我还太遥远:dizzy:），读完master如果走不下去再去乖乖考证。

读读今年jm的paper看看自己还有兴趣继续没，叙事逻辑论证方法观察点etc

business version of statistics is far from enough, you need a more rigorous version of probability & statistics course, which is normally not provided by business school.

here what I mean for a more solid prob and stat course, is normally in the math/stat department, for which include a calculus based probability course (e.g. double integration for calculating Pr (X1 > 0.3, X2 > 0.6) and also convolution and transformation of pdf, e.g. X ~ something, Y = 2X^2+6 ~ what?)
and a normal junior level statistics course include not only various type of tests (e.g. t-test, chi-square and etc), but also various type of convergence, like CLT, WLLN, and some of the theorem behind used to proof them.


Analysis do help. If you don't have enough time for reach up to real analysis level (senior UG), taking the intro one (junior UG) will also be useful. But honestly I will say it is.....they are difficult indeed. They are likely to be the most difficult course you will had taken within your life.

lz的经历和我一样，我是美本大三会计转的Econ。不同的是我一开始就在minor stats和math，不过转专业以后仍然感觉被虐的像狗一样。。。建议lz慎重考虑，如果就是不喜欢acc可以离开，如果没什么目标就打算换个方向读读的话你会体会到转专业其实是一件消耗极大地事情。我觉得lz要是读了Econ MA就很难有经历再去准备cpa的考试了。

谢谢～
一年的Prob&Stat sequence 是指把intro to prob和sta 合二为一的课程吗？我们学校的calculus based prob 叫 Statistical Analysis，但我没找到单独的intro statistics，请问你有大致的description吗？

real analysis学校把它算作master课程，数学专业只要求到intro analysis，课程介绍是Elementary combinatorial probability theory, random variables, probability distributions, and moments.不知道能不能看出来level。

I agree with you, but I am sure I will regret if I don't try.

层主前辈是打算读econ master之后决定转专业的吗，转专业被虐是指本科还是后来读研？

绝大多数学校统计系本科都有种课 第一学期学probability 第二学期学statistics
课程名各式各样 但内容应该差不多 经典教材是DeGroot & Schervish, Probability and Statistics
可以上amazon看下目录 第一学期cover 前六个chapter 第二学期cover后半本书的主要内容
你发的那个description 基本上相当于这课的probability 部分


至于analysis 经典教材是Rudin, Principles of Mathematical Analysis 不过对于初学者读起来非常困难 需要对数学证明有一定经验 可能乍一看目录觉得和微积分差不多 其实差距挺大的
这课对于学graduate level的经济课以及更高级的数学课很有用
这门课非常耗脑力

1 year Prob&Stat sequence = one semester course in calculus based prob + another one semester course in statistics. Check the year 1 or 2 core course of the stat major in your university, and they must have that.

I think it is really strange that the calculus based prob is called statistical analysis, I guess it is very likely that you make it wrong, and it is the statistics course indeed.

If mathematics major are only required to do up to intro analysis.....then do till that only.
normally an intro analysis course will go through topic like Sequences, Metric spaces, Continuity in IR, Differentiation, and etc....
while the topic you listed here sounds like a intro prob course indeed.
