My Life as a Graduate Student in ASU - First Semester
It’s been a while since I last posted an article. I’ve now settled in the U.S., taking care of essentials like banking, insurance, getting a car, and starting my courses.
Returning to student life feels refreshing, so I’m determined to study smarter than I did in Taiwan. I’m also thrilled to be taking some fantastic courses at ASU.
My Life This Semester
This semester, I’ve been working on data analysis and statistical simulations using R language for my courses each week.
In addition to coursework, I’ve learned how to perform text sentiment analysis with Python, thanks to the ASU Library’s Data Science and Analysis department.
Courses
BST601: Biostatistical Theory/Inference
This course provides a solid foundation in mathematical theory, covering topics like Poisson distributions (commonly used in count regression) and Bernoulli distributions (used in logistic regression).
A basic understanding of calculus is required, which makes sense since many of these theories are calculus-based.
BST602: Applied Multi-Level/Longitudinal Analysis
This is my favorite course this semester. The professor engages with students frequently, encouraging us to think critically and recall core concepts from regression models.
The training in descriptive statistics has been challenging but invaluable. Previously, I taught myself data analysis using classical machine learning models but didn’t delve deeply into the mathematical meanings behind these models.
BST604: Computational Biostatistics
This course feels like an extension of BST601. We complete assignments in R, often comparing theoretical probability density function (PDF) calculations with results from R packages. We also use Monte Carlo methods to calculate PDFs for specific functions.
How I Study Smarter
I connect new concepts with previously learned theories to reinforce my understanding. I use ChatGPT for discussions: I ask specific domain-related questions (e.g., on statistics or R language), review the responses, and test my understanding by explaining concepts back to ChatGPT. I prioritize breaks and avoid studying when I’m tired to maintain focus and efficiency.
