Beijing. Shipping agents. On the side I make my own products and try to sell them outside China. This is where I keep the process, the thinking, and the results.
Each post records the information I had at the time and the reasoning behind each judgment, so that on rereading I can locate the step where it went wrong. Data posts come with a reproduction repository containing the scripts and aggregated data; every conclusion can be recomputed. If your results differ from mine, let me know.
