How to calculate relative risk from GAM model in mgcv package?
Hi R users,I am a beginner in the use of R. I need urgent help for my

I have daily air pollution parameters PM10, PM2.5 CO, NO2, SO2, and O3. I
also have daily hospital admission numbers. Taking into account the effect
of weekends and holidays, I would like to used generalised additive model
(GAM) to explore the relationship between daily patients admissions, and

Gluster failure disk is full
Hi,
I have a 3 way gluster 4 setup. I had a "mishap" of some sort and I lost
node no2. There was and is 660gb spare on no1 and no3 but no2 is so full I
cannot mount it at boot, nor manually. I was making a 80gb VM so no idea
what happened, nor how to fix it?

general question about dropping terms of glm model fits
...rently helping someone with their statistical analysis of a
count survey, I stumbled upon a very basic question upon model optimization:
when fitting a model like:
model<-lmer(abundance~(x+y+z)^3,family=poisson,...)
in which x,y,z are continuous abiotic parameters such as po4
concentration, no2-concentration, which terms / interaction terms would
you recommend removing FIRST?
the ones of lowest significance (i.e. the ones with highest p-value) OR
the ones with the most complex interaction structure (even though
p-values may be low-ish)?
another question just popped in my mind:
