The Good oL’ Titanic Kaggle Competition pt. 1
After that I began playing around with logistic regression. So far, none of my attempts at logistic regression have improved my score but I have some ideas for tomorrow (already reached my submission limit for today). I do realize now that I need to have a plan with my logistic regression models, I need to determine which features have the best ...

HOW TO HOST YOUR SHINY APP ON AMAZON EC2 FOR MAC OSX
In a previous post I had mentioned that I would provide a hosting guide for Shiny applications so other people wouldn’t have to suffer through all the same issues I did when trying to do this. Just for reference, I am running OSX Yosemite. For the SSH client you’ll be using Terminal, for the SFTP client you’ll be using Cyberduck. Much of t...

using the httr package to retrieve data from apis in R
For a project I’m working on, I needed to access residential electricity rates and associated coordinate information (lat/long) for locations in the US. After a little searching, I found that data.gov offers the rate information in two forms: a static list of approximate rates by region and an API, which returns annual average utility rates ($/...
