This is the home page of Trond Reitan at
CEES, the department of biology,
the university of Oslo. The links in the left side of the page will
take you to the contents that I've made available here. If you are
interested in C++-programming, please check out my library. The same
link also contains a few nice graphing programs for linux and a couple
of regression programs.
- I have made a relativly short intro to Kalman filtering (via more general
filtering on hidden Markov processes). It is available as
PowerPoint and PDF.
- GSA 2015 presentation about
bivalve and brachiopod extinction/origination rates and how they're connected.
- Pollinator analysis presentation, as
shown at the SCAPE and CEES 2015 conferences.
- Simbies - A simulation and analyzis program suite
for the paper "Do not divide count data with count data; a story of
pollination ecology" by Trond Reitan and Anders Nielsen.
- Hare-lynx page: Here I describe a project
of analysing predator-prey abundance data using stochastic differential equations
coming from theoretical ecology. Data and code is included.
- Statistics course 3 for hydrologists.
Will be held at HS, NVE.
- Statistics course 2 for hydrologists.
Will be held at HM, NVE.
- I'm holding a lecture on identifiability at
here's a PowerPoint and
PDF version of this lecture.
advanced usage and
a "under the hood" view of my
stage-discharge rating curve program (using Bayesian regression).
- Statistics course for hydrologists.
Held at NVE.
- My lecture for CEES concerning hare/lynx analysis, where I
use ecological models (stochastic differential equations) in order to
look at the capture data for hares and lynx in Canada.
- Statistics course for hydrologists.
Held at Statkraft.
- Pacman evolution - A lecture about
a programming experiment I did, with evolution in a graphical
- Survival analysis - a workshop/crash course
in the subject. Presentation, exercise text and R help code is found here.
- Material for my gene correlation analysis.
Searches for groups of correlated gene expressions in
microarrays. Can also be used for other analysis where the
object is to find groups of correlated objects.
The analysis is Bayesian, so if you know before the data that some
genes/objects probably are correlated, this knowledge can be used.
- Time series crash course, held for
- Layered. This is an online resource page for
my layered stochastic differential equation apparatus, which
will be used in an upcoming paper. The apparatus was originally
used for analyzing microfossils, but I've later generalized it,
and used it on water temperature data and my own body weight.
- My thoughts on allometry. This is a
lecture I held for a couple of biologists in order to discuss
allometry, the relationship between one body part and another.
- Material for my lectures and exercises in
Bayesian statistics for ecologists at Finse.
- My presentation at Kent
university next week. PDF version.
- Source codes and example files
for multistate system reliability
analysis with stochastic component (un)availabilities.
- Source codes for analysis of layered linear stochastic differential
equations are found here. A test file is
included. The program must be altered in order to accomodate other
data structure, different number of sites, other layering structure etc.
- Inference programs for dynamic rating curves can be found
- MCMC routines for R available here. Also, two
example files, linear regression and
- My presentation of layered evolutionary modelling is available in
PowerPoint and pdf format.
- I've made a presentation about my research conterning Bayesian
rating curves. It's available in PowerPoint and
- An expanded version of my spam lecture (26/4) is available in pdf format,
here. PS: only in norwegian. PSS: The
translation from OpenOffice to pdf was not perfect.
- There's marginally illuminating look at a
quantum bouncing box in two dimensions, available
- A course in Bayesian statistics and simulation technique that I
held at NVE, 5/12-2007.
