Show HN: Covid-19 Projections, Simple Logistic and Exponential Models

9 点作者 an_d_rew大约 5 年前
Hello, HN!<p>There have been a <i>lot</i> of COVID-19 from various sites, but a common complaint is that simple things like log-scaling population counts are are infrequently done.<p>So I decided to do it:<p><a href="https:&#x2F;&#x2F;covid19.fernandes.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;covid19.fernandes.org&#x2F;</a><p>I&#x27;ve aggregated the JHU (per Country) and NYT (select US states) data and plotted them under two models: simple exponential growth and simple logistic growth. The plots are updated as the JHU and NYT data is updated (thanks, GitHub actions!).<p>A big challenge has been the <i>writeup</i> because the exponential model implies horrific things, but the logistic model seems... well, perhaps overly optimistic, probably due to the lack of solid testing data. So it&#x27;s really difficult for the layperson (and even many experts!) to interpret.<p>Anyway, comments and constructive critique are welcome, especially suggestions on how and what to say on the &quot;copy&quot; to help &quot;ordinary people&quot; understand and interpret the plots.
