In an effort to get into the habit of writing down my thoughts, I am, ill-advisedly, experimenting with starting a blog. I expect to cover mainly topics in statistics, econometrics, machine learning, and numerical computation, with some chance of also entertaining thoughts on how these relate to macroeconomics. Actual macroeconomics will be kept to a minimum, as that topic attracts sufficient attention online already, except in the case that I lack the self-control to avoid arguing on the internet. I also expect that unless I begin to use it for brief summaries and comments, this won’t be frequently updated, and may die an untimely death in the face of more pressing matters. The main uses are likely to be working through concepts that I only partially understand, in order to clarify my thoughts and to provide a benchmark so that when or if some kind of an understanding is reached, there will be a public record on the internet of my ignorance intellectual evolution. If the record of such a process also serves to draw the interest of the reader into the topics that preoccupy me and direct them to more reliable sources, all the better.
