Creating a Presentation with LaTeX Beamer – Tables

Tables of information can be included in a LaTeX beamer presentation in the same way that they would be incorporated into any other LaTeX document. The tabular environment is used and, if necessary, the tables could be numbered but this probably doesn’t make as much sense as labelling and numbering tables within an article or

Multidimension bridge sampling (CoRe in CiRM [5])

A repulsive random walk

Matt Asher posted an R experiment on R-bloggers yesterday simulating the random walk which has the property of avoiding zero by quickly switching to a large value as soon as is small.
