## How Fast the Fastest Human Would Run 100m?

April 16, 2014
By

Ethan Siegel wrote a post entitled The Math of the Fastest Human Alive five years ago, using regressions. An alternative is too use extreme value models (I wrote a post a long time ago on the maximum length of a tennis match using extreme value theory a few years ago). In 2009, John Einmahl and Sander Smeets wrote a great article...

## Errors on percentage errors

April 16, 2014
By

The MAPE (mean absolute percentage error) is a popular measure for forecast accuracy and is defined as     where denotes an observation and denotes its forecast, and the mean is taken over . Armstrong (1985, p.348) was the first (to my knowledge) to point out the asymmetry of the MAPE saying that “it has a bias favoring estimates...

## Side-by-Side Box Plots with Patterns From Data Sets Stacked by reshape2 and melt() in R

Introduction A while ago, one of my co-workers asked me to group box plots by plotting them side-by-side within each group, and he wanted to use patterns rather than colours to distinguish between the box plots within a group; the publication that will display his plots prints in black-and-white only.  I gladly investigated how to

R 3.1.0 (codename “Spring Dance“) was released today! You can get the source code from http://cran.r-project.org/src/base/R-3/R-3.1.0.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course. The full list of new features and bug fixes is provided below. Upgrading to R 3.1.0 You can

## categoryCompare Paper Finally Out!

categoryCompare Paper Finally Out!I can finally say that the publication on my Bioconductor package categoryCompare is finally published in the Bioinformatics and Computational Biology section of Frontiers in Genetics. This has been a long time coming, and I wanted to give some background on the inspiration and development of the method and software.TL;DRThe software package has been...

## Stationarity of ARCH processes

$\phi$

In the context of AR(1) processes, we spent some time to explain what happens when  is close to 1. if  the process is stationary, if  the process is a random walk if  the process will explode Again, random walks are extremely interesting processes, with puzzling properties. For instance, as , and the process will cross the x-axis an infinite number...

The question is: can we automate scientific discovery, and what might an interface to such a tool look like. I’ve been experimenting with automating simple and complex data analysis and report generation tasks for biological data and mostly using R and LATEX. You can see some of my progress and challenges encountered in the presentation
