Modify your rutledge function to print x, and you'll see the values of
high printed. x should be 1:45.

Dear All,
I am struggling to develop a model to forecast the daily expenses from
a bank account.
The daily time series consists (obviously) of non-negative numbers
which can be zero in the days when no money is taken from the bank
account.

Hi,
I am a beginner with statistics and R and have no clue on how to model my
data. I have collected information on seed traps (ID) that includes the
habitat type (Hab) and different measures of distances. Also I have applied
a modularity analysis, so that the seeds traps are grouped into modules.

This is hopeless, since you never seem to listen to our advice,
therefore this will be my very last try:
So you actually need local advice, both for statistical concepts and R
related. No statistics software can estimate effects of variables that
you observed to be constant (e.g. 0) all the ti

I ran a glmm in lmer with a random factor for nestedness. Spatial dependence
seems to have been accommodated by model. However I can't add a variance

I forgot to add that yes, I've done my homework, and that it seems to me
that answers pointing to zero-inflated Poisson (and negative binomial)
are irrelevant ; I do not have a mixture of distributions but only part

Dear all,
I have a dataset where I reduced the dimensionality, and now I have a
response variable with probabilities/proportions between 0 and 1
Thank you all for the very fast answers.
My proportions come from a factor analysis on a number of binary variables,
in order to avoid having to fit 12 logistic regressions on the same dataset.
By scaling the obtained scores to 0 and 1, I get weighted averages of the
