Thanks. In this case below, what is "x"? I tried rownames(out) which did
not work.
Sorry. Does this sound like homework to you?

Below is part a regression printout. How can I use "grep" to identify
rows headed by variables (first column) with a certain label. In this
case, I like to find variables containing "somewhath",
"veryh",?"somewhatm", "verym", "somewhatc", "veryc","somewhatl",
"veryl". The result should be an index 6:13 or

Write values on y axe
Hi,
I have values on y axe from 0.0001 to 3.086. When I do plot I have writen
values: 0.001, 0.050,1.000 ..., but how I can write on graph the minimum
value and maximum value, with all decimals (I don't want to use the format
1e-0x)? I am using log scale.
For example, if I have the values:
0.0001
0.0015
0.0256
0.0236
....
0.0201
2.9668
3.0086
I need have each 'x' value put on y axe,

constrOptim - error: initial value not feasible
Hello at all,
working with a dataset I try to optimize a non-linear function with

arima on defined lags
Dear all,
The standard call to ARIMA in the base package such as

coxpath() in package glmpath
Hi,
I am new to model selection by coefficient shrinkage
method such as lasso. And I became particularly
interested in variable selection in Cox regression by
lasso. I became aware of the coxpath() in R package
glmpath does lasso on Cox model. I have tried the
sample script on the help page of coxpath(), but I
have difficult time understanding the output.
Therefore, I would greatly appreciate if

Confidence intervals for prediction based on the logistic equation
Greetings,
We are performing a meta-analysis of mink pup survival data versus
chemical concentration. We have modeled percent survival successfully
using nls as shown below and the plot. What we need to do is construct a
confidence interval on the concentration at which we get 50% survival
(aka the EC50, although we may want other percent survivals in the
future). My first question is, what seems

Hi Jack, thanks for the numbers. Any chance of analysing why gcc does better on

Thank you very much for your reply. Your code work well with this example.

False alarm. For some reason that I have not yet been able to figure out, these tests run significantly more slowly when I run them during the daytime, which I did for that run. I checked a few of the worst regressions reported here and they all recovered in subsequent

Dear Spencer and Prof. Fox,
Thank you for your replies. I'll very appreciate, if you have any ideas concerning the problem described below.
First, I'd like to describe the model in brief.
In general I consider a model with three equations.
First one is for annual GRP growth - in general it looks like:
