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

I am afraid you will even regret more if you try that.......and then find not suitable as the cost (both time & money) is very very high.

I don't mean that you should not work on such a master and target for a PhD. I just mean........have a bit more taste about it before you make serious investment, e.g. spend tons of tuition doing a master that's don't have much value other than further study.

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？
谢谢你的建议。

我现在已经在读PhD了。我想说的是转专业之后你会发现和那些一开始就在准备读Econ PhD的同学的基本功差一大截，会非常辛苦。想想看，你本科前三年读的课程对申请一点用也没有，相当于白白浪费了三年的时间。而且Econ是一门理论学科，三年所带来的沉淀还是有很大区别的。大部分从大一开始励志读PhD的学生大二时候已经学过intro to analysis和中级的课程，大三开始已经在准备更高阶的数学课和Econ课程了。如果lz现在的速度去上课，最快恐怕也就是在本科毕业以前学完requirement，不太可能有时间继续深入高阶课程。等到上master时候会比较辛苦。

this is my search from school web

Statistical Analysis
Description: A calculus-based applied statistics course. Descriptive statistics; discrete and continuous random variables; probability distributions including binomial, Poisson, normal and t-distributions; one- and two-sample hypothesis tests and confidence intervals; simple linear regression and correlation.

this sounds to be a two semester course right?

Statistical Analysis
Description: A calculus-based applied statistics course. Descriptive statistics; discrete and continuous random variables; probability distributions including binomial, Poisson, normal and t-distributions; one- and two-sample hypothesis tests and confidence intervals; simple linear regression and correlation.

this is a one semester course, which seems to cover both calculus based probability and statistics together.
I wonder how deep they can go into.



Introduction To Analysis
Description: The real number system, topology of the real line, limits of sequences and functions, continuity, differentiation, and integration.

This one is what we mean for introduction to analysis, which is normally a junior level course (i.e. year 1 or 2)
and seems there are no real analysis course in your department at bachelor level, but only at graduate level.

Real Analysis
Description: Metric spaces, limits, sequences and series, continuity, differentiation, Riemann-Stielties integration, uniform convergence of sequences of functions.

indeed this real analysis course is normally in senior UG level, and graduate level real analysis will go further.



while these two sounds to be a good sequence of prob and stat.....but don't know why is 4XX

Introduction To Mathematical Statistics I
Description: Elementary combinatorial probability theory, random variables, probability distributions, and moments.

Introduction To Mathematical Statistics II
Description: Principles of statistical inference, estimation, and hypothesis testing.










not to be offense, but what I found while reading the program structure of your university's in math & stat is that, I find that they are quite XXX when compared to the normal standard.

Some of the course that should be in junior UG are offered at senior UG (with 3XX or 4XX), while some senior UG level course are already in graduate level (5XX). Please adjust this back when you read others comment, and also when considering from the point of admission.

大一只上了原理，大二double major 后一直有上eco课程但目前为止也都还只是基本的。由于我在商院开设的business econ，不知道除了数学方面的课以外是否在eco的课程上也和正常的econ本科有很大不同？
很佩服层主的坚持和决心，我记得你是在madison读的master，现在的phd生活顺利吗？

thanks for reminding.
so i should take Introduction To Mathematical Statistics 1&2 rather than Statistical Analysis?
ok, i will.

I think so, but seems they require that one to be the pre-req....
This sequence is a next to a must I will say.

Introduction To Mathematical Statistics I
Description: Elementary combinatorial probability theory, random variables, probability distributions, and moments

Introduction To Mathematical Statistics II
Description: Principles of statistical inference, estimation, and hypothesis testing.



I will suggest following also:

Time Series Analysis
Description: Methods for analyzing time series including: decomposition of time series, seasonal adjustment methods, index numbers; forecasting including causal models, trend models, smoothing models, autoregressive models, moving average and integrated models.

Introduction To Analysis
Description: The real number system, topology of the real line, limits of sequences and functions, continuity, differentiation, and integration.

A course in Numerical Analysis, Differential Equation, Optimization and Stochastic Process are also recommended (but seems that your school really don't have a good math department that even don't have the last 2 course out of these 4 offered.......well since you won't have enough time anyway, suffer it in master then......or you can consider doing it elsewhere like exchange, coursea, summer school or etc...)

I guess this really depends on which master......
I will say the intro one (Statistical Analysis) is 100% a must, while this 1 year long sequence.....:
I guess those master that are more solid and quantitative will require them, while those less academic / more applied one will not require that as a must.

Given that you plan to do a PhD, I will say, DO IT.
Since even it is not a 100% must, it will be still very useful.
Just like you will like to do the Intro to Analysis, Time Series......

If possible is skip the pre-req, skip it to save the tuition (?)

if i take some classes in the last semester when i have already submitted my application, will these classes be useful as same as the classes that i have submitted records in application?

and may i ask another question,
exchanging to another university to finish its standard econ undergraduate program or applying to the econ master, which one do you think will be the better?

Q1. Common sense will already tell you that a course without grade is of course less powerful than a course with grade in application. But the key point here is indeed......you need the knowledge to further study.

Q2. I consider master > extending to UG econ course.
