Package spatstat updated to version 1.18-1 with previous version 1.18-0 dated 2010-03-10

2010-03-19T08:16:00+00:00

Title: Spatial Point Pattern analysis, model-fitting, simulation, tests
Description: A package for analysing spatial data, mainly Spatial Point Patterns, including multitype/marked points and spatial covariates, in any two-dimensional spatial region. Also supports three-dimensional point patterns. Contains functions for plotting spatial data, exploratory data analysis, model-fitting, simulation, spatial sampling, model diagnostics, and formal inference. Data types include point patterns, line segment patterns, spatial windows, pixel images and tessellations. Point process models can be fitted to point pattern data. Cluster type models are fitted by the method of minimum contrast. Very general Gibbs point process models can be fitted to point pattern data using a function ppm similar to lm or glm. Models may include dependence on covariates, interpoint interaction and dependence on marks. Fitted models can be simulated automatically. Also provides facilities for formal inference (such as chi-squared tests) and model diagnostics (including simulation envelopes, residuals, residual plots and Q-Q plots).

Senators’ ideal points against Obama vote

2010-03-19T04:04:03+00:00

I added another plot to the output generated by my overnight ideal point scripts: a scatterplot of estimated Senate ideal points against Obama vote share in their state (color coded by party, local linear regression overlays by party, labels for some big residuals).

I suppose I’m surprised by the way that the loess curve for the Democrats flattens out to the left of 50% Obama vote share. It is an interesting picture to stare at and speculate as to why that is the case: party whipping by the Dems, agenda control (distorting our estimates of the ideal points of Dems in ranks, say, 35-60), lack of fit by the one-dimensional model, some combination of all this, something else…

Outliers: Coburn (R-OK), Demint (R-SC) and Ensign (R-NV) among the Reps; Lieberman (really a Dem?, and a positive residual), and two big negative Dem residuals, Brown (D OH) and Harkin (D IA).

R Project selected for the Google Summer of Code 2010

2010-03-19T01:15:00+00:00

Earlier today, Google announced the list of accepted mentor organizations for the Google Summer of Code 2010 (GSoC 2010). And we are happy to report that the R Project is once again a participating organization (and now for the third straight year) joining a rather august group of open source projects from around the globe.

An R Wiki page had been created and serves as the central point of reference for the R Project and the GSoC 2010. It contains a list of project ideas, currently counting eleven and spanning everything from research-oriented topics (such as spatial statistics or automatic differentiation) to R community-support (regarding CRAN statistics and the CRANtastic site) to extensions (NoSQL, RPy2 data interfaces, Rserve browser integration) and more. I also just created a mailing list gsoc-r@googlegroups.com where prospective students and mentors can exchange ideas and discuss. As for other details, the Google Summer of Code 2010 site has most of the answers, and we will try to keep R-related information on the aforementioned R Wiki page.

Old wine in new bottles

2010-03-18T23:36:23+00:00

In a rare appearance at OTB, I discuss the recycled Schumer-Graham immigration bill. It’s like a Hot Tub Time Machine back to 2006, when another president was heading into midterm elections facing an overseas military quagmire, own-party lawmakers in marginal districts who were distancing themselves from his policies, and deteriorating poll numbers!

Webinar: High-Performance Analytics with R and Microsoft HPC Server

2010-03-18T20:40:28+00:00

On April 14 I'll be giving a new webinar in partnership with Microsoft on High-Performance Computing with R. I'll be focusing on the new parallel programming capabilities of REvolution R Enterprise 3.1 for Windows, and how to use the features of Microsoft HPC Server to enable computing on clusters. Here's the complete agenda, and you can register at the link below.

Statistical data analysis is a key part of the operations of just about every business today. But as data sets get larger, analyzing trends or generating predictions becomes more and more of a challenge.

If you're doing predictive modeling today and find that you can no longer use all of your data because of size limitations, or the computations are taking too long for you to take action on the results, then the parallel-processing capabilities of Windows HPC Server can help. In this webinar, we'll introduce the R language for statistical computing, and show how the easy-to-use parallel programming capabilities of REvolution R Enterprise work with a HPC cluster to cut processing times by an order of magnitude or more.

We'll give practical examples of how to speed up many kinds of analytic computations, from simple summary statistics to cutting-edge tools like ensemble predictive models.

Audience: Programmers, researchers and analysts who need to process large volumes of data for data mining, statistical analysis, or predictive analytics

Doin' it wrong

2010-03-18T05:26:56+00:00

A mildly bemusing job ad that came across the wire today:

The Department of Government and Sociology invites applications as Course Redesign Coordinator. This is a non-tenure track, limited term, faculty position with the rank of Lecturer. The term is for a period of two years subject to re-approval and budget in year two. The successful applicant will lead a pilot study to redesign the introductory course in Political Science which is a required course in the university’s core curriculum. The position is responsible for producing an initial design for offering the course to larger sections while remaining consistent with the university’s public liberal arts mission; teaching one large (150 minimum) section of POLS 1150, Politics and Society, each semester; collecting and analyzing comparative data on student satisfaction and performance in larger course settings; supervising a graduate assistant and undergraduate student mentors ; preparing recommendation s for final redesign and implementation; conducting a required Freshman Seminar for departmental majors.

To review: this institution prides itself on its “public liberal arts mission” and excellent classroom instruction. So it is going to hire a non-tenure-eligible faculty member (who may not even have a doctorate) to come in to figure out some way to cram 150 students into an introductory course without any loss of quality. And once they’ve done this favor for the existing faculty, since they aren’t on the tenure track, they will be summarily kicked to the curb.

Somehow I do not expect this experiment to end in a rousing success.

O'Reilly at OSBC: The future's in the data

2010-03-18T04:23:55+00:00

Tim O'Reilly's keynote talk at OSBC this evening was thought-provoking to say the least. The title of the talk was "The Real Open Source Opportunity", and the surprise for me was that he wasn't talking about Open Source software. Tim's insight, and it's a profound one, is that the next frontier for freedom and openness -- and indeed, the way we'll live our lives -- lies with data.

Why? The world in which open source software was born is very different from the world we're heading to. Less than a decade ago, a major concern of the computing world was that much of the capability and innovation was locked up in closed software held by major corporations, like Microsoft. Open-source software addressed that. But look where innovation lies today: companies like Google (and few others) --built on the backs of open-source technology, mind you -- can now perform tasks that not long ago were the realm of science fiction. Today, you can speak a question into a tiny handheld gadget, and find out where to get good pizza. But think for a moment how Google can do this reliably and quickly: it's their data. They've amassed a massive, proprietary database of search queries, written text, and voice samples that allow the Google Voice Search app on the iPhone (and algorithms in Google's cloud servers) to distinguish "pizza" (said in on a noisy street in a Jersey accent) from "piece of" or the city "Pisa". Tim was careful to point out: it's not the closed algorithms that make this work. Peter Norvig from Google has said it himself: Google doesn't have better algorithms than everyone else. They just have more data.

Tim asked a question to the audience: "Could anyone in the Open Source community build the infrastructure to deliver Google Voice Search?" The response: a stony silence. The implication? Vendor lock-in is lo longer about proprietary source code. It's about massive, hard-to-replicate data sets -- making Google a potential Microsoft of the next decade. The corollary? The future will be about who has the most data, and who is able to extract meaning from it and deliver it in real time.

So how can we avoid data lock-in in the years to come? Tim suggests that it may be the underdogs of these new cloud-based tools that become the allies of open source data applications. Ironically, it may be Microsoft, lagging today in the domains of search, maps, and speech recognition, that may be the biggest ally in making the associated data services available openly. Google certainly has no motivation to do so; on the contrary, in areas like local search where they once linked to third-parties like Yelp, they're now providing their own data exclusively. Another opening likely comes from open standards for data sharing, like the Gov2.0 initiative.

The implications are profound, not just in terms of lock-in but also in the areas of privacy. (Interesting privacy implication: did you know that it's possible to identify a specific appliance, like a Kenwood dishwasher, from the "DNA" of its power draw signal? Consider that when your power company tracks your power usage with e-meters.) But when the operating system of the future is the entire internet, which license you use for open source software somehow seems like small beans compared to the open data issue.

Update: The slides from Tim O'Reilly's keynote are now available: Open Source in the Cloud Computing Era

OSBC blogging

2010-03-17T17:06:34+00:00

I'm at the Open Source Business Conference in San Francisco today and tomorrow; I'll report in with updates after the talks. I'm particularly looking forward to the panel discussion on The Shifting Open Source Opportunity moderated by Ashlee Vance, the New York Times reporter who wrote the major story on R last year. (Interesting aside: I learned recently that that story was the most-emailed at the NYT the week it was published.) REvolution board member Zack Urlocker is also on the panel.

If you're at OSBC yourself, drop in and say hi. You can find REvolution at the North Bridge Venture Partners booth in the exhibit hall.

Update: forgot to mention I'm live-tweeting the conference, too. Follow me at @revodavid and others at the #osbc hashtag.
