PS 初稿，不知这样的构思和写法是否可行，求助大家和Ziye 姐帮忙修改和提意见。谢谢！
Statement of Purpose (Mathematical and Computational Finance)
In2008, the crisis of international finance had swept over the globe and causedtremendous damage to people. In recent years, investment and risk-managementare more and more come in to people's attention. I choose Mathematical and Computational Finance as mygraduate program and future career notonly because the program as a technology that balances the benefits and the risk in financial fieldhas the vast prospects for development but also because I have strong background in computer programming,mathematics and modeling.
The firsttime that I was attracted by programming was in our academic seminar, when Iwas assigned a task to count the 5000th number in Fibonaccisequence. Although now I know that the arithmetic is very simple, I was veryimpressed by the simple and effective arithmetic to solve seemly supertime-consuming problem at that time. Besides for its effectiveness, I had agreat time in figuring out the right algorithm; this process of reasoningbrought me back the happy time I had in the series books of Summers G.J. Mylater gaming programming entitled as the prince saving the princess andsuccessfully independent programming called as “Mini-Matlab”. Furtherstrengthen my interest in programming, and convince me of choosing programmingat least at part of my future career.
I wasfascinated by finance in mathematics of finance courses，mathematicalfinance professors brought me to this charming world，professor XXX showed us how Merton modelworks for ranking the corporate securities and how the amazing daily BDT modelbuilt up by excel-based Macro can price the option; professor XXX showed us in forty-five minuteshow to just use the simple expectation theory to deduce famous Black-Shaleformula which was awarded Nobel Price. I deeply feel the charm of mathematicsin finance. In seminar，I was assigned a project to pricean option which is available to hedge a bond portfolio. This project requiresExcel based Visual Basic which is a language I don’t know at that point. Mybackground of C language helps me to pick it up quickly, and further to builtup a monthly Black Derman Toy model to price a put option successfully.
In my junior year，because my excellent academic records, Iparticipated in a research program sponsored by the University of XXX HonorProgram “Study concerning the variation of nitrate concentration in the XXXRiver, XXX”. The project is used for controlling the variation of nitrateconcentration，because that concentration is crucial indetermining the quality of the drinking water supplied to the City of XXX. Iwas the only student and my advisor is Professor XXX. This project involved use of time series models and the R programmingenvironment. As I never learn Time series theory before，while I waslearning myself Time series theory from a book written by my advisor while wasdoing the project. Myresponsibility is that utilized R programming to develop a timeseries with external variables model (ARIMAX) tomeasure Nitrate concentration. In order to find a suitable distribution forthe residuals, I tried many distributions. At the same time I was fascinated bymathematics modeling which will be an indispensable part of my future career. Paper ofthe project soon will be published on Advanced in Water Resources.
After these courses and practices, I decide to be aquantitative analyst in financial field. I choose it not only because it catersto my needs for challenging life but also because it is very close to people’sdaily life, helping people make wise decision for their investment and hedging.The utilization of mathematic modeling and programming asanalytical tools makes me occupied in my fond field again and gives me aplatform to exert my talents.
The University of XXXoffers excellentMathematicaland Computational Finance program that attracts me notonly because of strongtradition of interdisciplinary study and tutorialsystem which underpins a culture of close academic supervision and careful personalsupport for students, but also because ithas intense curriculum to strength my skills in finance, computation, mathematic modeling and programming. Since Ijust start to experience the charm of finance field, my finance background isnot enough. I am trying to catch up all necessary knowledge in the financialmarket before my possible chance to study in the University of XXX. Iconfident University of XXX Mathematical andComputational Finance Program and my own hard work pave me the right roadtowards my long term goal.
