LaTeX and Sweave

December 1, 2009
By

LaTeX is a typesetting language that is known for its beautiful mathematical formulas. It is similar to HTML in that you write your document in plain text and process (or compile) it to create a postscript or PDF file. You will need to download a LaTeX processor for your platform. On Windows, TeXnicCenter (http://www.texniccenter.org/) is

Using doc-view with auto-revert to view LaTeX PDF output in Emacs

When I am authoring a document in Emacs, such as a report or my CV, it is useful for me to compile the source file periodically to see what the resulting file PDF looks like. I used to run a separate PDF viewer to look at the output, but I now have a complete Emacs

R: Function to create tables in LaTex or Lyx to display regression model results

Most people using LaTex feel that creating tables is no fun. Some days ago I stumbled across a neat function written by Paul Johnson that produces LaTex code as well as LaTex code that can be used within Lyx. The output can be used for regression models and looks like output from the Stata outreg

Introducing: Orthogonal Nonlinear Least-Squares Regression in R

With this post I want to introduce my newly bred ‘onls’ package which conducts Orthogonal Nonlinear Least-Squares Regression (ONLS): http://cran.r-project.org/web/packages/onls/index.html. Orthogonal nonlinear least squares (ONLS) is a not so frequently applied and maybe overlooked regression technique that comes into question when one encounters an “error in variables” problem. While classical nonlinear least squares (NLS) aims

simulation by inverse cdf

Another Cross Validated forum question that led me to an interesting (?) reconsideration of certitudes! When simulating from a normal distribution, is Box-Muller algorithm better or worse than using the inverse cdf transform? My first reaction was to state that Box-Muller was exact while the inverse cdf relied on the coding of the inverse cdf, like

Calculating Churn in Seasonal Leagues

One of the things I wanted to explore in the production of the Wrangling F1 Data With R book was the extent to which I could draw on published academic papers for inspiration in exploring the the various results and timing datasets. In a chapter published earlier this week, I explored the notion of churn,

The average Stripe employee! Congrats to Alyssa!

Recently, my colleague and fellow blogger Alyssa Frazee accepted a job at Stripe. All of us at JHU Biostat are happy for her, yet sad to see her go. While perusing Stripe’s website, I found the About page, where each employee has a photo of themselves. I’ve been playing around with some PCA and decompositions,
