Appointments can be exported from outlook (win XP) abd ical (Mac OS X) just by drag and drop to your favorite mail program. It is just one click here on the attachment to import the date here (Lufthansa already knows that but you may use this hint in your company to get the inventor award). BTW The screenshot shows another neat idea of integrating dynamic Doodle feeds.

Funny? Laughable? Ridiculous?

www.cell.com/current-biology shows humour

Human emotional expressions, such as laughter, are argued to have their origins in ancestral nonhuman primate displays. To test this hypothesis, the current work examined the acoustics of tickle-induced vocalizations from infant and juvenile orangutans, gorillas, chimpanzees, and bonobos, as well as tickle-induced laughter produced by human infants.

Ghost in your genes

was an earlier title of a BBC documentation about gene methylation. While running today an analysis of segregating methylation marks, I have major difficulties to find out the status of the human epigenome map. The Sanger site seems to be down for a long time, there aren’t any updates of the AHEAD consortium, the site of the Epigenetics Society is largely uniformative, methDB gives me “information about the research situation in France and why French scientists are in conflict with the current government”, an EU network excellence has only a fashionable website while another EU project is even not fashionable. Or do I miss something??

What is the best logistic model?

I have never heard a formal lecture answering this question even after many years in epidemiology. It should be parsimonious of course to avoid too many missings but seems largely a subjective approach to keep or drop a variable. It was therefore quite helpful to find now an online lecture that exemplifies a sound approach – check out unc.edu/courses/2006spring. I already used anova to compare models (at least since my move from SAS to R) while using AIC is something that I am adding now to my toolbox. Continue reading What is the best logistic model?

Mac OS X running Sigmaplot

screenshotI haven’t found any replacement yet for Sigmaplot that is offered only as a native Windows application. Even buying a copy of Aabel didn’t bring me back the fast and intuitive plotting capabilities. Running Sigmaplot under Parallels is a pain using too much of the system ressources while Crossover failed to start up even after following these step-by-step instructions. Finally, with Crossover 8, it seems that a win98 bottle can run Sigmaplot 9!
