Landing on Big Data

I woke up light headed in the morning and immediately reached out to my phone. To my surprise, I deleted the Instagram app without thinking much, and so far that has been the greatest move that I have done to kick start my day.

So my day today consists of several tasks that I have written down. I need to find additional courses to take, for the limit of 21 credits. Actually I was thinking that maybe I should take it easy this semester, but then I think that I can always push myself a bit further. In a spare moment, I think I might regret it, because deep inside I want to rest rather than panicking. Also I need to make sure that this semester record will be good. So far I want to know that I will perform well, and I shouldn’t let anything stand in between to challenge that effort.

One of the courses that I was considering taking is Topics in Economics (Financial Data Analytics) offered in School of Political Science and Economics. the course consists of Linear Regression, Classification Model, Lasso and High-Dimensional data, as well as Tree-based method. Indeed, I have not heard about any of them except Linear Regression. I would be a little bit worry about whether I should pursue a learning in Advanced Statistic or not. So I was looking around the web to make a judgement for myself. Although it gave me a brief look at what are the objectives and uses of the knowledge, it turns out not to be that exciting. Last class on Cost-Benefit Analysis was very helpful, but I thought that I wouldn’t make it without spending a ton of time focusing on that and jeopardize my other classes.

Regardless, it gave me this insightful view on what statistician has to deal with on maybe daily basis. After landing on this PDF provided by S. Gadat about Lasso and High Dimensional data, I was struck by how little I know and how inadequate my skill is to take on the class. This type of modeling are possibly frequently used in the financial market, where new data input and output are updated every second, with huge trend to draw and analyze. I’m still wondering whether being a financial analyst would be who I want to become, or indeed it is a brain-drain job that have high volatility, with high level of stress and reward. But I think if I put my full effort in it, I will be able to generate a great amount of value.

I just think that virtually I can do anything and achieve everything I wanted. But it won’t happen all at once.
