Feed: SAS Blogs. Author: Rick Wicklin. During an epidemic, such as the coronavirus pandemic of 2020, the media often shows graphs of the cumulative numbers of confirmed cases for different countries. Often these graphs use a logarithmic scale for the vertical axis. In these graphs, a straight line indicates that new cases are increasing at an exponential rate. The slope of the line indicates how quickly cases will double, with steep lines indicating a short doubling time. The doubling time is the length of time required to double the number of confirmed cases, assuming nothing changes. This article shows one ... Read More

Feed: R-bloggers. Author: R on Stats and R. A classic epidemiological model: the SIR model Before diving into the real-life application, we first introduce the model that will be used. There are many epidemiological models but we will use one of the simplest, the SIR model. Tim Churches’ explanation of this model and how to fit it using R is so nice, I will reproduce it here with a few minor changes. The basic idea behind the SIR model (Susceptible – Infectious – Recovered) of communicable disease outbreaks is that there are three groups (also called compartments) of people: those ... Read More

Feed: Redis Labs. Author: Guy Royse. Like many software engineers, I enjoy a good game of Dungeons & Dragons. I love powering up my character and facing increasingly more powerful foes. Doing this right requires gold and experience. And the best way to get those things is a good old-fashioned dungeon crawl. If you need some context on D&D, this video might help. The short but overly simplified version: in D&D you explore underground complexes, fight monsters therein, and take their gold. Unfortunately, dungeons aren’t set up for the convenience of adventurers like us. Sometimes the monster is challenging but ... Read More

Feed: Matillion. Author: Ashley Lozito; Data democratization is one of the key trends in 2020. As we know, the amount of data is growing exponentially – and so is the number of data silos per organization. But more people inside of an organization want to be data-driven in their decision making. As a result, companies of all sizes will need to make this siloed data available across the business so users can more quickly get to valuable insight through data. In fact, it’s not really optional – businesses need to democratize this data to stay competitive.   Citizen Data Professionals need ... Read More

Feed: R-bloggers. Author: Learning Machines. Learning Machines proudly presents a guest post by Martijn Weterings from the Food and Natural Products research group of the Institute of Life Technologies at the University of Applied Sciences of Western Switzerland in Sion. The topic of this post will be the fitting with the R-package optim. Food? That sounds like a rather unlikely match for writing a post on a blog about quantitative analysis, however, there is a surprising overlap between these disciplinary fields. For example, whether you model the transport of a flavour molecule or transport of a virus, the type of ... Read More

Feed: SAS Blogs. Author: Robert Allison. Now that COVID-19 is spreading in the US, I thought it might be helpful to view the data at a more granular level. Follow along as I plot the county data on a map and discuss how the color-binning can influence people's perception of the data. Maps like this can be helpful, as they can help you track where the virus has spread - and perhaps more importantly, where it hasn't spread. County Data First I needed a source for the US county-level coronavirus data. After a bit of web searching, I found that ... Read More

Feed: SAS Blogs. Author: Rick Wicklin. A cumulative curve shows the total amount of some quantity at multiple points in time. Examples include: Total sales of songs, movies, or books, beginning when the item is released. Total views of blog posts, beginning when the post is published. Total cases of a disease for different countries, beginning when the disease passes some threshold (such as the 100th case) in each country. If you plot multiple cumulative curves on the same graph, you can compare the different songs, blog posts, or countries. How do the sales of one song compare with another ... Read More
