These counts are then added onto statically generated baselinedata for each city to produce a full synthetic data set. A consistentfraction of the modeled infection cases are recorded as daily clinicvisits. An infection is initialized in a single random city and infection countsare recorded in each city for a fixed period of time. Transportation between cities is modeled similar to. Finally,city sizes are calculated based on an observed three-quarter power-law scaling relationship with the sampled degree distribution.Each city is represented as a customizable stochastic compartmentalSIR model. Unconnected graph components are each joinedto the largest component using linear preferential attachment.

We generate atransportation network as a Chung-Lu random graph that preservesthese scale-free relationships (Figure 1).First, given a power-law exponent and a desired number of cities,a probability mass function (PMF) is generated that mirrors theexpected degree distribution for the given power-law relationship.Values are then sampled from this PMF to generate an expecteddegree (number of connected cities) for each city in the network.Edges (airline connections) are added to the network probabilisticallyas described in. demonstrate the power-law relationships betweencity population, air traffic, and degree distribution.

The generator is developed in the R programming languageand produces data compatible with the popular `surveillance’ softwarepackage.MethodsColizza et. have shown that epidemic spread isdependent on the airline transportation network, yet current datagenerators do not operate over network structures.Here we present a new spatial data generator that models thespread of contagion across a network of cities connected by airlineroutes. Please use a modern, up-to-date web browser and check your security settings.ObjectiveTo develop a spatially accurate biosurveillance synthetic datagenerator for the testing, evaluation, and comparison of new outbreakdetection techniques.IntroductionDevelopment of new methods for the rapid detection of emergingdisease outbreaks is a research priority in the field of biosurveillance.Because real-world data are often proprietary in nature, scientists mustutilize synthetic data generation methods to evaluate new detectionmethodologies. This tool requires JavaScript to generate datasets, which is not currently available. To make this process easier for everyone, I have written the program below to generate datasets! It is modeled on the chapters of my book (so, for example, you can generate a dataset to help you with the content in Chapter 4), but you can also use it for specific statistical tests if you know what you’re looking for.ĭataset Generator Settings Chapter/Statistical Test: You then need to work through the problem by hand yourself to demonstrate those steps to students. As an instructor, creating datasets is not much easier – you need to use data generation techniques and then test iteratively to ensure the numbers you end up using provide a meaningful test.

The tool on this webpage is designed to help you with this problem.Īs a student, if I wanted to test myself on statistical skills, I would need to create a dataset – and I could throw numbers into a table easily enough – but then I’d have no way to know if I was right after conducting analyses. If you’d like to teach or learn about statistics from a practical, hands-on perspective that students can relate to, I strongly recommend it!Īs a statistics student and as a statistics intructor, one of the things I found most frustrating was a lack of datasets to test my knowledge and to provide self-test material to my students.

It’s accompanied by click-by-click video demonstrations of all skills in both SPSS and Excel, tied closely to chapter contents, plus an online random dataset generator for learners to test their computational skills (and instructors to generate problem sets!). It’s a concise, one-semester introduction to the topic based around a chapter-by-chapter exploration of how small business owners can solve practical problems with statistics.

Inspired partly by my success at explaining How to Compute ICCs in SPSS on my blog, and partly because I think significance testing is usually not well-understood by most students in statistics courses, I wrote a statistics textbook entitled A Step-by-Step Introduction to Statistics for Business, published by SAGE.
