    Data Scientist

    Argentina - Last active: 8 days ago - Tests: 4 - Portfolio: 6

    What are the most relevant variables? How are they related (if any)? What values must they take in order to explain some event? I'm familiar answering this kind of questions, as well as making graphs to show information, build automatic systems to process and make predictions, and all kind of data science stuff (founded the site datascienceheroes.com). Further than working as a consultant, I can teach you how to build solutions through R. From Data Science theory to the building and application of your own predictive models, based on your data. Found the e-learning course: http://datascienceheroes.com/learning.html. I've been doing data analysis for the last 9 years, working in several industries such as telco, banking, farming, financial, social network analysis, bio-technology, oil and NGOs. My education is based on Information Systems (holding a PhD degree) Contact me if you have questions to address through data, or if you want to learn R in a very didactic way.
