I am keeping some information on my setup in my L^AT_EX page.

I am keeping some information on my setup in my Latex page.

L^AT_EX is a document preparation system, not a word processor, that allows the creation of complex documents (specially with lots of math). There are several systems available (either free or quite costly), and I normally use in my mac. I also keep a PC in my office, where I use MikTeX, which is an excellent alternative for machines running Windows. Some good additional software and references for L^AT_EX are:

• Since mid 2006 all my LaTeX writing has been done in a mac. I use TexShop, which is an excellent front-end/editor.
• I did test LyX, which is a more graphical front-end to LaTeX. Document importing was not great, and I could not see a great advantage over working with a simple editor.

I am keeping some information on my setup in my Main/Latex page.

I have started moving my resources to a separate page.

• Since mid 2006 all my LaTeX writing has been done in a mac. I use TexShop, which is an excellent front-end/editor. The distribution that I am using behind TexShop is gwTex, installed using Gerben Wierda’s i-installer.
• I have also been testing LyX, which is a more graphical front-end to LaTeX. I am not yet sold on the idea, but I will give it a more thorough testing while writing course notes in June 2007.

Splus and R

Splus is an excellent general statistical software, that I use for models not covered by AS Reml. Until a few years ago I used SAS, but the licensing system is awful (one does not buy SAS, but rents it; specific analysis tools need to be licensed separately) and the integration of new analysis technologies takes forever. Splus seems to be much more flexible: no need to renew the license every year, maintenance is cheaper, most statistical procedures come with the main license, a very active community developing new functions and, if the developers go bankrupt, one can always go to the R system (an open source implementation). In fact, I mostly use R these days and the only things that I miss from Splus are interactive graphics and easy imports from spreadsheets.

Update: now back in academia I have again access to SAS, which is the most popular statistical software at the university.

A few links to Splus/R resources:

A highly probable forecast in case there are problems with the link: windy and cloudy (but there is always hope).

Python is a really nice scripting language that I use for rapid development and prototyping. Python and Python Numerical extensions (NumPy) allow the functionality of ‘Matlab style’ programs, with the advantage of a higher level language and it is for free! There are tools for creating stand-alone versions of the programs, graphical user interfaces, CGI scripting and whatever you may have in mind.

• Download Python Numerical Extensions (NumPy).

• StatPy: Statistical Computing with Python, an excellent list maintained by Tom Loredo.

ASReml

AS Reml is a very powerful statistical software developed by Dr Arthur Gilmour from New South Wales Agriculture, with help from a bunch of other researchers. It is specifically designed for fitting mixed models for large datasets, with unmatched model flexibility and high speed. It is far faster than SAS, S-Plus and similar software. It has recently been included as the calculation engine for GENSTAT, but I still use it in stand alone mode (I don’t have a license for GENSTAT). It has extensive documentation, with a manual that is over 200 pages long.

The growing amount of resources for AS Reml that I have compiled prompted me to reorganize the material. Now you can find all things AS Reml in the ASReml cookbook?. This is an ever increasing source of information, so visit it often.

Splus

Splus is an excellent general statistical software, that I use for models not covered by AS Reml. Until a few years ago I used SAS, but the licensing system is awful (one does not buy SAS, but rents it; specific analysis tools need to be licensed separately) and the integration of new analysis technologies takes forever. Splus seems to be much more flexible: no need to renew the license every year, maintenance is cheaper, most statistical procedures come with the main license, a very active community developing new functions and, if the developers go bankrupt, one can always go to the R system (an open source implementation).

A few links to Splus resources:

• S-Plus and R Libraries, Functions, and Documentation maintained by Frank Harrell, Vanderbilt Department of Biostatistics, Vanderbilt Medical Center.
• Brian Ripley’s site, home to the MASS library and of the ‘S programming’ and ‘Modern Applied Statistics with S’ books.
• S poetry is a free book (in PDF format) geared towards people programming Splus rather than using the point and click interface.
• Home page of the S news email list, including the archives. In my opinion, the search function is not great, and it works much better to use Google using a query like: this one. Including “s-news” will limit the results to material related to Splus.
• Some Splus materials from the US Naval Postgraduate School.
• A site explaining Splus and R for ecologists, with emphasis on multivariate statistics in vegetation ecology (including PCA, CCA, etc.).
• Quantum Forest contains some posts on issues I have faced working with Splus and R. The post on COM connection seems to be quite popular.

• I prefer to create Acrobat PDF documents as output, using pdftex. You can find a tutorial about PDF creation (including internal and external hyperlinks) in Ringlord’s page. An additional useful resource is this page. Have a look to their hyper.pdf document.
• There is a lot of useful information at the TeX User’s Group web site.

C++

I was using a bit of C++ to implement prototype programs initially written in Python. It is quite an interesting language that, when using the standard libraries, makes a lot of sense. However, I have moved to Visual Basic 6 and VB.net (in the near future): much easier to use. In spite of this, these links might useful for someone else.

• Links to the C++ FAQ lite and to a detailed C++ FAQ language pages.
• Metrowerk’s Codewarrior C/C++/Java compiler page (the one I’m using now).
• Accelerated C++ by Andrew Koenig and Barbara Moo. A good introductory book to C++ programming.
