Comparing means and trends in short time-series
Dear R-list,
I have a statistical problem with the comparison of short time-series,
representing densities of fish in different streams. For each stream (6 in
total, here below showed only part of the dataset) I have 8 years of density
data, as follows:
year density stream
1 2000 0.51 stream1
2 2001 0.87 stream1
3 2002 0.68 stream1
4 2003 0.56 stream1
5 2004 0.50 stream1

Optimization
Dear R-list,
I'm trying to estimate the relative importance of 6 environmental variables
in determining clam yield. To estimate clam yield a previous work used the
function Yield = (A^a*B^b*C^c...)^1/(a+b+c+...) where A,B,C... are the
values of the environmental variables and the weights a,b,c... have not been
calibrated on data but taken from literature. Now I'd like to estimate the

Trouble about the interpretation of intercept in lm models
Hallo,
yesterday I was puzzled when I discovered that I
probabliy miss something in the interepretation of intercept
in two-way lm models.
I thought that the intercept, using the default contr.treatment
contrasts, represents the mean of the group of observations
having zero in all column of the model.matrix.
It turns out not to be case
To be more more clear I am attaching a short example:

Zero-inflated neg.bin. model and pscl package
Dear list,
I'm currently trying to develop a model to assess clam yield potential in a
lagoon. I'm using the zeroinfl function of the pscl package to fit a
Zero-inflated negative binomial model, given the high occurrence of zero
counts.
I don't understand from the sentence in the pscl guide "Zero-inflated count
models are a type of two-component mixture model, with a component

setdiff datframes
hi,
I have 2 files example 1 and example 2 and would like to know what is in

difference between nls and nlme approaches
Hallo,
I have a question that is more statistic related than
about nlme and R functioning.
I want to fit a complicated nonlinear model with nlme with several
different measures of transpiration taken on each of the 220 trees
grouped in 8 families. The unknown parameters of the model are three +
their variances (and covariances). I want to estimate the variances
among families of the

[LLVMdev] Buggy assertion in APFloat::convertFromHexadecimalString
Hello.
When running clang in Debug mode, I am getting an assertion failure when
parsing the following line:
float ko = 0x1.1p0;
Apparently, the recent changes in the use of StringRef haven't been
propagated to all places. Please find attached the trivial patch.
Cheers,

densCols: what are the computed densities and how to create a legend
Hi,
I'm using the densCols function for a scatterplot and cannot figure out 1) how to extract the computed densities, and 2) how to create a legend based that represents the upper and lower ranges of the densities.
For example:
movers.den <- densCols(move$x, move$y)
table(movers.den)

OHLC Plot with EMA in it
Hi there
I have some timeseries data which I plot in a OHLC Plot. In the same
plot I'd like to have the EMA of this timeseries. I tried to add the
EMA point to OHLC with lines(), but this doesn't work. Has anyone an
idea how to handle it?
