The Remarkable Similarity of Covid-19 Infection Waves throughout the World
I have been modeling covid-19 cases and deaths in all areas of the world for the past six months. I built the coronavirus forecasting dashboard which makes predictions for covid cases/deaths for all countries and US states. In this post, I will explore the remarkable similarity of covid infection waves across many areas of the world.

More than 99.9% of the Pfizer Vaccine Placebo Group did not get a severe case of covid
The Pfizer vaccine trial has 43,000 participants. Exact breakdown between treatment and placebo groups is not given, but they do provide the number of covid cases in each group. Currently, there are 162 covid cases in the placebo group.
Assuming a 50/50 split, 99.25% of the placebo group did not get covid.
Additionally, only 9 in the placebo group had a "severe case" and no one died. That is 99.96% in the placebo group did not have a severe case.
Caveats
We need to know the overall...
Instantly Beautify Matplotlib Plots by Viewing all Available Styles
In this post, you'll learn about the different available matplotlib styles that can instantly change the appearance of the plot. Let's begin by making a simple line plot using the default style. This simple style is often the first (and sometimes only) style that many people encounter with matplotlib not realizing how easy it is to choose others.
import matplotlib.pyplot as plt import numpy as np x = np.arange(-2, 8, .1) y = .1 * x ** 3 - x ** 2 + 3 * x + 2 fig, ax...Automate Publishing of Jupyter Notebooks as Medium Blog Posts with jupyter_to_medium
I am very excited to announce the official release of jupyter_to_medium, a Python package that extends Jupyter Notebooks, allowing you to automate the process of publishing them as Medium blog posts.
Motivation
I've published dozens of blog posts on Medium myself with all of them beginning as Jupyter Notebooks. Manually converting them to Medium posts was a fairly lengthy, painstaking process. One particularly painful process was inserting tables, which Medium does not support, into...
Official Release of bar_chart_race - A Python Package for Creating Animated Bar Chart Races

Minimally Sufficient Pandas
In this article, I will offer an opinionated perspective on how to best use the Pandas library for data analysis. My objective is to argue that only a small subset of the library is sufficient to complete nearly all of the data analysis tasks that one will encounter. This minimally sufficient subset of the library will benefit both beginners and professionals using Pandas. Not everyone will agree with the suggestions I lay forward, but they are how...
