I just put my functions to interact with the EIA's API into a R package which I've called 'EIAdata'. The package is available here: EIAdata_0.1.tar.gz. Once downloaded, you can install it with
R CMD INSTALL EIAdata_0.1.tar.gz while in the same directory.
The package contains the functions
getEIA which will get data categories/series IDs, and the time series data for a given series ID, respectively.
I posted a new working paper HERE. It is a short letters type paper---so it is a quick read. In the paper we show four standard portfolio performance measures (Sharpe Ratio, Jensen's alpha, Information Ratio, and Treynor Ratio) all rank portfolios consistently (all measures have a preference for portfolios with a greater number of stocks). The implication is, it doesn't matter which portfolio measure you use, each will afford a very similar ranking for a given set of portfolios.
Here is a great basic introduction to email encryption from the Free Software Foundation: https://emailselfdefense.fsf.org/index.html
You can watch the World Cup live (or should I say 'en vivo') at Univision here: http://deportesenvivo.univision.com/. Of course, the play by play is in Spanish. If you want to English play by play, a Bloomberg article has a work around.
I just listen to the Spanish announcers -- if you know a bit of Spanish you can generally get the idea of what they are saying. And anyway, they are much more fun to listen to when a goal is scored.
A little while ago, my Debian sid system stopped mounting CDs. Shortly thereafter it stopped mounting USB devices also. After searching around a bit I found a solution here (the problem was with Consolekit): https://lists.debian.org/debian-user/2011/10/msg01252.html
The solution is to create a file
etc/polkit-1/localauthority/50-local.d/consolekit.pkla with the contents:
Identity=unix-user:your username here
of course replacing your username here. Also create
/etc/polkit-1/localauthority/50-local.d/udisks.pkla with the contents:
Hope this helps if you run into the same issue.
This is the spread as of Tue Jun 17 21:07:38 2014. The spread remains in the lower half of its range given expectation that gas in storage will rebound.
The widowmaker spread is the difference between NG for March and April (March less April). It gets its name from being fairly volatile, usually in response to changes in working gas in storage and cold weather (late winter storms).
The EPA has recently announced a proposal to reduce carbon pollution. Specifically the EPA has set state targets for emission rates (the number of pounds of carbon emissions per megawatt hour of electricity produced). A summary of the percent reduction in proposed emission rate by state is below.
The proposed reductions range from a maximum percent reduction of 71.82% in Washington state, to a minimum percent reduction of 10.58% in North Dakota.
Of course, looking at percent reductions loses scale -- which is paramount in this case. If we look at total yearly proposed carbon reductions (in million metric tons) we see the largest reduction is by far in Texas (87 million metric tons per year) with Florida and Pennsylvania following.
