Hi,
I am wondering if anyone knows of an easy way to fit a saturated model
using the sem package on raw data? Say the data were:
mtcars[, c(mpg, hp, wt)]
The model would estimate the three means (intercepts) of c(mpg,
hp, wt). The variances of c(mpg, hp, wt). The covariance
of mpg with hp

Error in nls(weight ~ cbind(1, exp(gamma * week)), weightData, start =

Hi all!
I have built a model to predict interactions with turtles and the model
includes an offset for effort:
ZIP-zeroinfl(Sturgeon~fMesh+fSeason+offset(LogEffort),dist=poisson,link=logit,data=data)
I wasn't clear about one aspect of the response to a similar question I
recently posted...I
Hi,
Try this:
dat1-read.table(text=
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3
300 2.2 3.3 2 4
,sep=,header=TRUE)
#Either
colnames(dat1)-c(2.5,3.6,7.1,7.9)
#or
colnames(dat1)-c(2.5,3.6,7.1,7.9)
#produce character column names
Another new question:
I want to be able to subset the data based on whether or not that data point
was recorded on a holiday. The is.holiday() function from the chron package
would be perfect for this. However, when I try it, the following happens
(I'm also using the timeDate package):
To add to Gabor's remarks:
This has nothing to do per se with R -- it is your insufficient
understanding of the underlying mathematical issues.
It is pretty trivial to do the plinear algorithm by hand. Fit linear
regressions
weight ~ lm(weight ~z)
where z is exp(gamma*week) for a suitable
just do this:
colnames(r)-substr(colnames(r),2,nchar(colnames(r)))
This will remove the X.
Later when you want to use the headed to plot something, cast it as numeric:
plot(colMeans(r)~as.numeric(colnames(r)))

Dear all
I am using lars package to do lasso in R. I dont undesrtand what max.steps
do?and how I can understand from the outputs to obtain the last steps in this
packagethanks for your helpbest

If you don't understand the methodology, why are you using it??
Use the glmnet package instead and read the supporting documents. If it's
too technical for you, consult a statistician or do something else.

I wrote a little function called first() to help with situations like
this. It returns a 1 every time an element of a vector is different from
the previous element, and a 0 otherwise.
first - function(x) {
L - length(x)
c(1, 1-(x[-1]==x[-L]))
}
sd - 1
residuals - c(1, 2.1, 3, 4,

I've not been following this thread but this seems ndependent from
previous posts. Try the following.

Hi,
I managed to use the attached data set and figure out the following:

The example you gave had only one split. If your real situation has three
splits, you'll have to take a look at testtree$csplit matrix and decide
how you want to define the new grouping variable. Here's one way to do it
