Cite in Lyx using Firefox + Zotero + Lyz

I have been using Lyx to mantain my CV. Knowig little about LaTeX and being lazy to learn LaTeX, I have been seeing Lyz as a friendly document editor on my desktop.

Then I learned how to use Zotero in 2010 and completed the migration from JabRef to Zotero.

Today I am using Lyz, a Firefox add-on that supplements Zotero to cite references in a Lyx document. Wonderful result. 

Here are the steps of how to get it done. Make sure you already are familiar with Lyx and Zotero and have installed Lyz in your Firefox. 

First, get basic setings done:

copy the pipe setting in Lyx and paste it to the setting of Lyz.

Step 2: select references you want to import to Lyx

Right click on the entries and click on "cite in Lyx". Suppose you like to put your citations in a separate bib file, say, test.bib, then let's create it.

Step 3: Insert the bib file into your Lyx document

Step 4: Insert references

Now you can insert references by right click on the entries selected in Zotero and see them show up in Lyx.

Here is the result:

Information Age: graduates driving industry adoption of R

Revolutions

Information Age recently published a feature article devoted to the R language, "Putting the R in analytics". Says author Pete Swabey:

Already popular in universities, there are signs that R is finding increasing adoption in the enterprise. This promises to lower the barriers of entry for advanced analytics, and may accelerate the mathemitisation of business management.

The article includes an overview of the history of R: its predecessor, the S language; the transition to open-source R; the pervasiveness of R in academia; and how this is driving an increasing rate of adoption in industry.

This popularity in academia means that R is being taught to statistics students, says Matthew Aldridge, co-founder of UK- based data analysis consultancy Mango Solutions. “We're seeing a lot of academic departments using R, versus SPSS which was what they always used to teach at university,” he says. “That means a lot of students are coming out with R skills.”

Finance and accounting advisory Deloitte, which uses R for various statistical analyses and to visualise data for presentations, has found this to be the case. “Many of the analytical hires coming out of school now have more experience with R than with SAS and SPSS, which was not the case years ago,” says Michael Petrillo, a senior project lead at Deloitte's New York branch.

Like many companies today, Deloitte needs to develop analytics with varied and large quantities of data, and is using Revolution R Enterprise for big-data analytics and API integration of R:

Deloitte is currently preparing a big data pilot using Revolution Analytics’ enhanced R product. “We are using the server-based version of Revolution R to investigate big data analysis capabilities,” says Petrillo.

“We are looking at integration options to [big data programming platform] Hadoop, as well as ability to integrate R code into other applications via a web services framework.”

I'm also quoted in the article discussing the big-data extensions of Revolution R Enterprise:

Smith argues that these enhancements are necessary if R is to be applied to ‘big data’, i.e. data whose volume, velocity and variability outstrip the capabilities of conventional relational databases.

More people want to learn statistics

 
More people want to learn statistics
Published on FlowingData | shared via feedly

Data is hot right now, so as you would expect, more people are signing up and applying to learn about it. Quentin Hardy for The New York Times reports.

At North Carolina State, an advanced analytics program lasting 10 months has, since its founding in 2006, placed over 90 percent of its students annually. The average graduate’s starting salary for an entry-level job is $73,000. Its current class of 40 students had 185 applicants, and next year’s applications are already twice that. In 2009, Harvard awarded four undergraduate degrees in statistics. Two graduates went into finance, one to political polling and one became a substitute teacher. There were nine graduates in 2010, 13 last year. They headed into Google, biosciences and Wall Street, as well as Stanford's literature department.

And in 2011, just about everywhere.

R is definitely the future (for those who can learn with English).

I had witnessed one of the founders of SAS moved to R in 2003 when I was a graduate student.

Now I am watching that the founder of SPSS moved to R and founded a new company based on R. (take a look of the last page of the pdf and see the intro of the author and the company:

Here is the slide that may also interest you:

Using R in academics can become a common language in the coming years. I am glad that I am on this exciting track and believe that you will feel the same.
I am also going to share these progresses with my students in the data analysis course using R next semester.
