ONLINE LEARNING

videolectures - biology, genetics, bioinformatics
eg.
http://videolectures.net/msht07_omont_gbba/

COMMENT: browsed videolectures.net yester and tried to watch cca 3 lectures on bioinformatics but the level of presentation was rather mediocre. topics interesting, but presented by some phd students in an uninteresting , hard-to-follow way.
but there is much more stuff, maybe i just didnt get representative sample, so hope to find something interesting.

statistics lectures, python, spss, R

a FANTASTIC COLLECTION of lectures on statistics - from basic concepts to advanced topics such as nonlinear regression. with examples.
- refers mainly to SPSS software, but this is marginal. MAINLY the mechanics behind the different tests is explained. VERY INSIGHTFUL.
