In this post, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the recent pandemic is analyzed. Several attributes about the presently recorded virus genomes are plotted and genetic mutations in the sequences are traced to identify probable phylogenies among the samples.
The following charts compare the number of deaths resulting from the CoVID-19 pandemic in various countries as of March 20th 2020. The daily totals are normalized by the population in each country to produce per capita numbers. Per capita numbers allow for more easy comparison between countries.

This chapter explores recessions in the United States of America. Datasets are collected from a variety of locations including the Federal Reserve Economic Data (FRED) and from the website of Yale professor and Nobel laureate Dr. Robert J. Shiller. A classifier model is constructed which predicts recessions and this model is analyzed for useful insights.
