These are short notes that I think are useful to share but will not become articles.
- Du, R.S., 2023. Learning the Evolution of Statistical Moments and Extreme Values from Data. [pdf]
- This note presents an easy way to diagnose the change in statistical moments and extremes from time-series data. It is simple to implement and versatile. We think it is most useful as a tool to quickly explore the time evolution of interesting quantities in data.
- Du, R.S., 2023. Plotting and Fitting Power-Laws. [pdf]
- Data following power-laws are ubiquitous in applied fields. In this note, we examine how one should diagnose the power-law exponent from data and how one should plot these data. One of our conclusion is that: linear regression on the log-log form of the data is not always appropriate.
