I hear a homophone here

The ABC’s online political correspondent Emma Rodgers reports on goings-on from the Coalition party room:

Mr Abbott’s comments were met with a hearty “here here” from many MPs in the room.

No. I’m sure what was said was “hear, hear”.

As Wiki notes:

It is often incorrectly spelled “here here”, especially on websites and IM.

Because it's Friday: Evolution in song

With thanks to my favourite science blog Bad Astronomy, the late great Carl Sagan sings again, this time on the topic of evolution. He's joined by autotuned Richard David Attenborough and Jane Goodall. Great stuff.

Package tgp updated to version 2.3-1 with previous version 2.3 dated 2009-12-26

Title: Bayesian treed Gaussian process models
Description: Bayesian nonstationary, semiparametric nonlinear regression and design by treed Gaussian processes with jumps to the limiting linear model (LLM). Special cases also implemented include Bayesian linear models, CART, treed linear models, stationary separable and isotropic Gaussian processes. Provides 1-d and 2-d plotting functions (with projection and slice capabilities) and tree drawing, designed for visualization of tgp-class output. Sensitivity analysis and multi-resolution models are supported. Sequential experimental design and adaptive sampling functions are also provided, including ALM, ALC, and expected improvement. The latter supports derivative-free optimization of noisy black-box functions.

Installing the homebrew package manager for OS X

homebrew is a package management system for OS X that allows you to install various open source packages much like macports. Homebrew claims to simplify some aspects of the package mangement process, for example, by putting packages in /usr/local/Cellar/PKG and symlinking into /usr/local rather than relying on a custom package database. Another advantage is that it aims to reuse any software already installed on your Mac instead of taking a self-contained approach, like macports, where you end up needing a custom version many libraries you already have (the duplication of which can sometimes come back to bite you).

Anyhow, I'm just installing it now to give it a shot. Here's how I installed it using git archive. I thought this two liner was worth sharing:

sudo chown -R `whoami`:staff /usr/local
cd ~/src
git clone git://github.com/mxcl/homebrew.git
cd homebrew
git archive --format=tar HEAD|(cd /usr/local;tar xf -)

Update: Actually, to get more out of homebrew, you might actually want to turn your /usr/local directory into a homebrew git repository. So instead of the above, you really want this:

sudo chown -R `whoami`:staff /usr/local
cd /usr/local
git clone git://github.com/mxcl/homebrew.git .

If you plan on contributing new formulas or otherwise tweaking homebrew, you might consider first creating a fork of the main repo and cloning that into your /usr/local.

Package rpsychi updated to version 0.1 with previous version 0.0 dated 2010-02-05

Title: Statistics for psychiatric research
Description: The rpsychi offers a number of functions for psychiatry, psychiatric nursing, clinical psychology. Functions are primarily for statistical significance testing using published work. For example, you can conduct a factorial analysis of variance (ANOVA), which requires only the mean, standard deviation, and sample size for each cell, rather than the individual data. This package covers fundamental statistical tests such as t-test, chi-square test, analysis of variance, and multiple regression analysis. With some exceptions, you can obtain effect size and its confidence interval. These functions help you to obtain effect size from published work, and then to conduct a priori power analysis or meta-analysis, even if a researcher do not report effect size in a published work.

Package rattle updated to version 2.5.21 with previous version 2.5.20 dated 2010-01-31

Title: A graphical user interface for data mining in R using GTK
Description: Rattle (the R Analytic Tool To Learn Easily) provides a Gnome (RGtk2) based interface to R functionality for data mining. The aim is to provide a simple and intuitive interface that allows a user to quickly load data from a CSV file (or via ODBC), transform and explore the data, build and evaluate models, and export models as PMML (predictive modelling markup language) or as scores. All of this with knowing little about R. All R commands are logged and commented through the log tab and so available to the user as a script file or as an aide to the user to interact directly with R itself. Rattle also exports a number of utility functions and the graphical user interface, invoked as rattle(), does not need to be run to deploy these.

Package AICcmodavg updated to version 1.06 with previous version 1.05 dated 2009-12-06

Title: Model selection and multimodel inference based on (Q)AIC(c)
Description: This package includes functions to create model selection tables based on Akaike's information criterion (AIC) and the second-order AIC (AICc), as well as their quasi-likelihood counterparts (QAIC, QAICc). Tables are printed with delta AIC and Akaike weights. The package also includes functions to conduct model averaging (multimodel inference) for a given parameter of interest or predicted values. Other handy functions enable the computation of relative variable importance, evidence ratios, and confidence sets for the best model. The present version works with linear models ('lm' class), generalized linear models ('glm' class), linear models fit by generalized least squares ('gls' class), linear mixed models ('lme' class), multinomial and ordinal logistic regressions ('multinom' and 'polr' classes).
Author: Marc J. Mazerolle . Special thanks to T. Ergon for the original idea of storing candidate models in a list.

Enkindle this (aka your Mass Effect 2 mini-review)

The sequel to Mass Effect has arrived and after about 10 days with the game I can honestly say that on virtually every dimension, ME2 is superior to its predecessor. Combat has been made a lot better; the decryption and electronics “mini-games” are much more engaging than playing Simon with the A-B-Y-Z buttons on the controller; and the voice acting and animation is a step up from the original. Overall the game definitely is more polished than its predecessor and feels more complete. After a short adjustment to the “new” rules of the ME universe, I found I really didn’t miss the elements of gameplay that were reduced or simplified.

Comparing two play-throughs of the game based on different saves from ME1, I could definitely feel a more ominous sense of Things To Come based on the differences in my actions in the two “pasts”; the consequences of past actions do not affect the main plot of ME2 drastically, but I have the sense that some of Shepard’s actions in the fight against Saren and Sovereign in ME1 will have major consequences in the third installment, as well as Shepard’s actions in ME2 of course.

ME2 definitely reflects its creators’ intentions to have a “darker” middle section of the trilogy; in particular, the lines of morality are blurred much more than in ME1 (where the only arguably morally-dubious “Paragon” choice was the decision to free the last of the rachni), and certainly what might be good for the galaxy doesn’t always align with what is right for Shepard. In the various missions you have to wrestle with the morality of taking actions to rectify past morally-dubious actions by others. If one faction seeks to impose its vision of Truth on another, is it morally acceptable to turn the tables on them and impose a different vision? Should a species that was mistakenly “elevated” without its consent be hobbled until that species’ people can mature sufficiently to deal with the technological advances that fell in their laps? Should a major piece of enemy technology be left intact for one particular race’s ethically-challenged black ops organization to discover its secrets, perhaps to be used not against the civilized galaxy’s common foe but for more immediate political advantage?

I would be remiss if I didn’t also discuss the humor that Bioware stuck in the game, including (but not limited to) self-deprecation about the excruciating elevator rides in ME1, a 22nd century take on Dirty Harry, an alien scientist who performs Gilbert and Sullivan, and ads for probably the worst production of Hamlet in recorded history. I laughed myself silly several times during the game; sometimes, it was because of something Shepard did (or a squadmate’s response to it), while other times it was just something bizarre overheard in the background—random banter between bystanders, for example.

My only quibbles thus far would be with the planet scanning part of the game (I don’t mind having to gather resources, but you’d think your multi-billion credit starship’s AI could scan for minerals on its own much faster than I could), the inability to revisit some of the interesting locations from ME1 (leading to some rather improbable coincidental encounters with important folks from those locations at other ports-of-call), and a sense that some locations just needed to be grander in scope—even some of the interesting places you visit are sealed once you complete missions in those areas, so you can’t really go and see what difference your actions made. I also miss a bit of the “party banter” from the previous game; given the much larger combination of squadmates possible for missions (and the lack of elevator rides for banter to take place), however, it’s understandable.

But the quibbles are more than offset by the positives of the game. ME2 was definitely top value for my entertainment dollar.

New package rpsychi with initial version 0.0

Package: rpsychi
Title: Statistics for psychiatric research
Version: 0.0
Date: 2010-02-14
Author: Yasuyuki Okumura
Maintainer: Yasuyuki Okumura
Depends: doBy, gtools
Description: The rpsychi offers a number of functions for psychiatry, psychiatric nursing, clinical psychology. Functions are primarily for statistical significance testing using published work. For example, you can conduct a factorial analysis of variance (ANOVA), which requires only the mean, standard deviation, and sample size for each cell, rather than the individual data. This package covers fundamental statistical tests such as t-test, chi-square test, analysis of variance, and multiple regression analysis. With some exceptions, you can obtain effect size and its confidence interval. These functions help you to obtain effect size from published work, and then to conduct a priori power analysis or meta-analysis, even if a researcher do not report effect size in a published work.
