<h1>CrimeDataAnalysis</h1>
<p>Repo for INRUG experiments using crime data.</p>
<p>INRUG members are working on a project to see what sort of conclusions can be drawn from public GIS and crime data from Spokane Washington.</p>
<p>The data can be found at <a href="https://static.spokanecity.org/download/gistransfer/pubdata/Crime.zip" class="uri">https://static.spokanecity.org/download/gistransfer/pubdata/Crime.zip</a></p>
<p>Supporting data can be found at <a href="https://my.spokanecity.org/opendata/gis/data/" class="uri">https://my.spokanecity.org/opendata/gis/data/</a></p>
<p>There is also a website called “CrimeWatch” that seems to have a lot of data, but we do not know if it is accessible right now (or if we even need it).</p>
<p>The NACJD <a href="https://www.icpsr.umich.edu/icpsrweb/NACJD/NIBRS/">National Archive of Criminal Justice Data</a> maintains copies of NIBRS data files from 2010-2014. However, only a few agencies in Spokane County submit the incident-level NIBRS data.</p>
<ul>
<li><a href="/NACJD_validation/README.md">“Does the NACJD include Spokane data?”</a></li>
<li><a href="https://www.icpsr.umich.edu/icpsrweb/NACJD/series/128" class="uri">https://www.icpsr.umich.edu/icpsrweb/NACJD/series/128</a></li>
</ul>
<div id="questions" class="section level3">
<h3>Questions</h3>
<p>Some possible questions with the dataset we agreed on include:</p>
<ul>
<li>Looking at Crime in zipcodes over time, does crime get worse before it get better?</li>
<li>Do we have legit sample sizes?</li>
<li>Do we have the granularity we will need to develop hypotheses?</li>
<li>What is the relationship between crime rate and marijuana legalization?</li>
<li>Are there distance (spatial) effects with crime rate and dispensaries?</li>
<li>What effect does building and population growth have on crime in different zipcodes (gentrification)?</li>
<li>Can we build an effect parameter that might inform more accurate taxation on companies regarding indirect community costs of building and growth?</li>
<li>Is response time to an incident predictable?</li>
<li>How is a communities demographics related to crime types and rates?</li>
<li>What are crime rate trends over time? Are they stable?</li>
<li>How predictable are crime rates at specific periods of time (by month)?</li>
<li>Can we do some sort of time series analysis (ie ARIMA)</li>
</ul>

<div id="getting-started" class="section level2">
<h2>Getting Started</h2>
<p><strong>First, make sure you fork the project on Github</strong></p>
<p>Clone the project in RStudio. After you make your additions and changes, make sure to push them back to your repository.</p>
<p>When you are ready to share something with the group, send a ‘Pull Request’ in Github to Joe, who will merge your changes with the original project. We can then update our ‘forked’ repos from the original project.</p>
<p>If you need help getting RStudio and git installed, the <a href="https://support.rstudio.com/hc/en-us/articles/200532077-Version-Control-with-Git-and-SVN">Using Version Control with RStudio</a> tutorial will help.</p>
</div>
<div id="using-sub-folders" class="section level2">
<h2>Using sub-folders</h2>
<p>In order to keep things organized, please create a sub-folder for each analysis or sub-project. These will hold all the R scripts, .Rmarkdown files and any other rendered reports used in your analysis. The final analysis should be rendered as an html_document within each sub-folder.</p>
<p>Data files should be kept in a <code>/Data</code> folder under the repository’s top folder. This will facilitate using the same data files. The <code>/Data</code> folder and contents are listed in the .gitignore file, which prevents them from appearing in the GitHub repository.</p>
</div>
<div id="publishing-an-html-report" class="section level2">
<h2>Publishing an HTML report</h2>
<p>The project has a web site located at <a href="https://JoeDumoulin.github.io/CrimeDataAnalysis/" class="uri">https://JoeDumoulin.github.io/CrimeDataAnalysis/</a>. The site pages are built using the new <code>render_site()</code> functionality in RStudio Preview (1.0+). More information is available on the <a href="http://rmarkdown.rstudio.com/rmarkdown_websites.html">R Markdown Websites page.</a></p>
<p>Links to your analysis can be added to the project page by:</p>
<ol style="list-style-type: decimal">
<li><p>Adding a link yourself. Just edit the ‘Index.Rmd’ file located in the repository root folder. Then use the <code>render_site()</code> function to re-build the index.html file. Send a pull request to Joe to merge your changes. This requires RStudio 1.0+ or higher.</p></li>
<li><p><a href="https://github.com/JoeDumoulin/CrimeDataAnalysis/issues">Posting an issue</a> to the main project repository. One of the team members with a newer version of RStudio can then add the link for you.</p></li>
</ol>
