epidemiology ode likelihood, hierarchical model
...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

Sensitivity analysis - looking a tool for epidemiologic research
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>

Making a new package: licence
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

box-and-whisker plots based on summary not data
Hi, Is it possible to produce box-and-whisker plots given that I have the median, interquartile and 5/95th centile values, but not the data from which they come? It seems that it ought to be possible to coerce bxp to do what I want, but I can't quite see how. Thanks, Matthew -- Matthew Vernon, Research Fellow Ecology and Epidemiology Group, University of Warwick
