Getting the through items from a has_many :through :uniq relationship
...and I want a DRY way to list the join model objects.
Currently, my objects include taxon objects, toxin objects,
data_object objects, and taxon_toxin_citation objects ("citation" is
another word for data_object). A taxon has many data objects, has many
taxon_toxin_citations, and has many toxins through
taxon_toxin_citations. As well as a taxon causing many toxins, a toxin
can be caused by many taxa. And there are many taxon_toxin_citations
linking a given taxon with a given toxin. (If anyone is interested in

zero variance in part of a glm (PR#11355)
In this real example (below), all four of the replicates in one
treatment combination had zero failures, and this produced a very high
standard error in the summary.lm.
=20
Just adding one failure to one of the replicates produced a well-behaved
standard error.
=20
I don't know if this is a bug, but it is certainly hard for users to
understand.

I would value your comments=20

Thanks

predictive logistic model cell-biology, non-dichotomous data
Hi everyone,
I would like to fit a predictive model to my data in order to compare
absorbance readings to a toxin standard. This data was obtained by exposing
red blood cells to different toxin concentrations, which lead to the lysis
of the red blood cells, increasing the absorbance (hemoglobin is freed). The
data has a sigmoid shape (see below), so I thought about fitting a logistic
model to the

Assign palette (e.g. rainbow) to a series of points on 1 plot
I have 11 vectors representing insect survival probabilities in
response to different levels of toxins at 10 concentrations
lx100=c(1,1,1,.8,.5,.4,.2,0)
day100=c(0,1,2,3,4,5,6,7,8)
lx90=c(1,1,1,1,.9,.8,.6,.4,.2,.1,0)
day90=c(0,1,2,3,4,5,6,7,8,9,10)
#...and so on10% and a zero (control) series
lx0=c(1,1,1,1,1,1,.9,.9,.8,.8,.6,.5,.4,.3,.2,.1,.1,0)
day0=c(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17...

Plot for Binomial GLM
Hi i would like to use some graphs or tables to explore the data and make
some sensible guesses of what to expect to see in a glm model to assess if
toxin concentration and sex have a relationship with the kill rate of rats.
But i cant seem to work it out as i have two predictor
variables~help?Thanks.:)
Here's my data.
