...ecessary. Required qualifications Your research background should be on a postdoctoral level, preferably on a professor level. You must hold extensive knowledge in theoretical statistics and also have attained substantial practical experience in the area of applied statistics. Experience with epidemiological research, including research based on use of register information and data obtained directly from study subjects, will be an asset. Ability to attract research funding is an advantage. Your qualifications will be assessed by an evaluation committee consisting of one internal and two external sc...

Course in STATISTICAL PRACTICE IN EPIDEMIOLOGY USING R ==================================================== Tartu, Estonia, 26 - 31 May 2005 The course is aimed at epidemiologists and statisticians who wish to use R for statistical modelling and analysis of epidemiological data. The course requires basic knowledge of epidemiological concepts and study types. These will only be briefly reviewed, whereas the more advanced epidemiological and statistical concepts will be treated in depth. Contents: --------- History of R. Language. Objects. Functions. Interface to oth...

Hi all, Please help on this. We will be teaching epidemiology using opensource software. What are R built-in functions or functions in available packages that are capable of doing these: a) Logistic regression (glm?) b) Conditional logistic regression c) Logistic regression with random effects d) Beta-binomial regression e) Poisson regression f) Weibull regression (eha?) g) Exponential

...early with a logNormal error. I would like to estimate the parameters of this model but as you can see using an ode solver package and the least square method to fit the model is not a good idea! Do you think it is possible to use a bayesian state space model with I as a Hidden state with this ode epidemiological model ? If not, it is at least possible to fit this ode model using a likelihood method instead of using least square ? Wich R package appears to be the most adapted ? Thank you! Melen

Stata users can rely on the very neat Episens package for sensitivity analysis. Briefly, it allows one to specify a diagnostic tool's sensitivity and specificity and take those into account when estimating a risk ratio, for instance. A full description of the package is available at <http://www.stata-journal.com/sjpdf.html?articlenum=st0138>

HI All, I have written and succesfully uploaded a new package. The licence it is under is 'GPL' --no version. My assumption is, since all the code is written in R the licence R used for R would affect the code (hence my "GPL" stands for "whatever version of the GPL R is under") I am happy with the licencing I used, but I'd like to ask if there is any transitive

Hello all, I have 300 clusters of fixed size 2 and I need to do resampling with replacement to run some regression models. I've searched through the archive and the only thing I found was that I could use 'boot()' function. but it's not clear to me how I can do this. Has anyone done it? I would very much appreciate your help, kelly

Hi, I am using the function "nomogram" in the rms package for survival analysis. How is the order in which variables determined and how can I change it? I use it with a cph() model.

Dear list, we are a statistical/epidemiological departement that - after a few years of rapid growth - finally is getting around to formulate a general data storage and retention policy - mainly to ensure that we can reproduce results from published papers/theses easier in the future, but also with the hope that we get more synergy betwe...
