Getting knitr to work with StatET

StatET (an Eclipse plug-in that can handle, among other things, R) offers support for writing Sweave (.Rnw) documents. This is done via the external tool dialog, where one creates a new “device” that takes in a document and runs it over appropriate functions and programs. In this case, Sweave and LaTeX. This dialog can, however,

What are the distributions on the positive k-dimensional quadrant with parametrizable covariance matrix? (solved)

Paulo (from the Instituto de Matemática e Estatística, Universidade de São Paulo, Brazil) has posted an answer to my earlier question both as a comment on the ‘Og and as a solution on StackOverflow (with a much more readable LaTeX output). His solution is based on the observation that the multidimensional log-normal distribution still allows

Writing reproducibly in the open with knitr

Sweave is something of a gold standard in reproducible research. It creates a dynamic document, written in a mix of LaTeX and R code where the results of the analysis (numbers, figures, tables) are automatically generated from the code and inserted into the resulting pdf document, making them easy to update if the data or

What are the distributions on the positive k-dimensional quadrant with parametrizable covariance matrix? (bis)

Wondering about the question I posted on Friday (on StackExchange, no satisfactory answer so far!), I looked further at the special case of the gamma distribution I suggested at the end. Starting from the moment conditions, and the solution is (hopefully) given by the system The resolution of this system obviously imposes conditions on those

I am finding myself more and more drawn to markdown rather then tex/Rnw as my standard format (not least of which is the ease of displaying the files on github, particularly now that we have automatic image uploading). One thing I miss from latex is the citation commands. (I understand these can be provided to
