A project for Reproducible Research

Just finished a big report for the course project. This was a part of Reproducible Research course on Coursera. https://www.coursera.org/course/repdata
The subject of the analysis was the most severe weather events and their consequences with respect to population health and economics.

A couple of interesting details.
I used generalized Levenshtein distance to handle raw data. Event coding in formal instruction and in real database weren't identical.
One of the tasks was to draw at least one plot. So I've made two US maps of weather events impact on population health and economics.

Hello!

Hello All!
This would be a blog about Data Science, User Experience and Web-analytics. My thoughts, ideas and events in my professional life. Thus I'm switching from my Russian blog http://olegdavydov.ru/ to here.
Stay tuned! :)
