Skills
Statistics:
Able to implement different univariate and multivariable analyses and interpret results properly. Familiar with different regression models, cox models, and longitudinal regression models.
Capstone project of Master degree: An ecology study on rubella by using dynamic model and Time Series Wavelet analysis. (Link: https://ry2an.github.io/2020/07/31/rubella/)
Course project: Analyzed relationship between self-reported mental status and obesity. Controlling for multiple chronic diseases with propensity score. Measured the validity of independent variable by using Cronbach alpha. All processes of data cleaning and analyzing are addresses on SAS 9.4. (Link: https://ry2an.github.io/2020/05/20/EPID622/) Presenting in English: https://www.bilibili.com/video/BV1D54y1Q77m
Repeated academic statistics analyses including: survival analysis (log-rank test and cox model), Poisson and Negative Binomial regression in SAS and R. (Details please foward to my blog.)
Course project: Analyzed game prices and ratings on the Steam store with longitudinal models. Game prices were treated as the time variable and publishers were treated as individuals. Linear mixed effect models and fixed effect models are used to handle continuous outcome and general estimated equation models are used to deal with discrete outcomes. (Link: https://ry2an.github.io/2020/01/11/Use-Longitudinal-Models-Analyzing-Steam-Games/)
Capstone project of Bachelor degree: By utilizing logistic regression in SPSS, the study revealed different factors that can influence the survival time of indwelling needles and their odds ratios on those influences.
Analyzing and Developing tools:
Excellent in R (with R markdown, ggplot2, lattice, xyplot, shiny and statistical testing) SAS, Python and MS Excel; familiar with, SPSS, and ArcGIS. Able to use github as a version controller. Able to write markdown files. Passed NCRE Rank I, II, and III (SQL: Excellent). Here are some cases:
[Connecting Four Chess] By utilizing ggplot2 and shiny package in R, a local chess game has been made with user interface and could run by editing and reading local files. (Link: https://github.com/Ry2an/connect_4_chess)
[R Tutorial] Made series of videos guiding others who want to learn about R software. (Link: https://space.bilibili.com/2477951/channel/detail?cid=133950)
[De Long Research Activity, Fudan University] Embed development by using Python and R software to create a program with user interface and implement some of the map-drawing functions in ArcGIS and used the cancer dataset from annual statistic reports. (Link: https://github.com/Ry2an/hanrygis)
[Crawler Programming] Crawling and describe infectious data from Shanghai Center of Disease Control’s website by using python and regular expression to identify. (Link: https://github.com/Ry2an/crawler_prac)
