...same 4 functional plant groups (funktGr), each represented by four species (the species are nested in the functional plant groups, because if I take species as a single factor I get 16 species, which is not true. in each chamber I have four replicates (pseudoreplicates) half of the plants got fertilisation (Fert), that means each plant got it's own fertilisation the response variable is biomass (g) Randomisation was done to plot and subplot level. I tried this: aov(log(g)~CO2*funktGr/Species*Fert+Error(Gruppe/CO2),data=biomass) the output is: Error: Gruppe Df Sum Sq Mean Sq F...

...selfmade" plot would be to tell boxplot not to plot boxes (sounds silly isn't it?). I've tried the option "boxwex=0" but the result is unsatisfactory. An example for a league table can be found in Marshall, Spiegelhalter [1998], Reliability of league tables of in vitro fertilisation clinics, BMJ1998;316:1701-1705, you may find it at http://bmj.bmjjournals.com Thanks in advance Eik Vettorazzi

Hello all! I have a problem that calls for a better understanding, than mine, of how lme() uses the random part of the call. The dataset consists of eleven field trials (Trial) with three replicates (Block) and four fertiliser treatments (Treat). Analysing for example yield with lme() is easy: m1 <- lme(Yield ~ Treat, data=data, random =~1| Trial/Block) giving estimates of

.... The approach is based on hierarchical models and relies on the use of advanced statistical software tools such as NONMEM, WINBUGS and R. To ensure the development of a conceptual research framework beyond the specific scientific questions being addressed by the working groups and enable cross-fertilisation of skills, a position has been created for a principal post doctoral fellow. This appointment also offers the possibility for a tenure track into an academic career. Requirements ________________________________ The post-doctoral fellow should have the following background and competencies:...

The main objective of this program is to evaluate how cardiovascular safety findings in phase III clinical trials correlate to long term safety in longitudinal (epidemiology) studies. From a methodological perspective, this investi...

Hi all, as part of adopting Rails in my company I had to go through the hassle of setting up a Rails production environment on Win32 system since we mostly use MS SQL as our database back end and also because we mostly dealing with customers who become green-blue-purple as soon as you mention Unix/Linux and run for the door. I also need to mention that most of our web applications are internal and
