Re: [R] Popularity of R, SAS, SPSS, Stata...
Am 20.06.2010 15:31, schrieb Muenchen, Robert A (Bob): I've been fiddling around with various ways to estimate the popularity of R, SAS, SPSS, Stata, JMP, Minitab, Statistica, Systat, BMDP, S-PLUS, R-PLUS and Revolution R. It's not an easy task. You can see what I've come up with so far at http://r4stats.com/popularity . I'm sure people will have plenty of ideas on how to improve this, so please let me know what you think. Your analysis is quite web-based. But to define what popular means is - I believe - hard. R is open source and very broad in its different applications so of course it generates much more e-mail and web traffic because there are many different uses and users. SPSS and Stata for example are closed and very specialized. You get support also directly from the company and do not necessarily need a mailing list. Does this mean that they are less popular? I'd say no. So the question I would raise here is whether it is a fair comparison? I know that is a sufficient statistics-subset like panel econometrics Stata is by far leading and for time series econometrics Eviews, Gauss in research. I would say that in the industry that I know plus in econometrics research those programs are much more widespread or popular. To measure their popularity I would say a industry-and-education-wide-questionnaire should be used. Plus it is not sufficient so I would also name Matlab, Gauss, Ox, Eviews from the areas of my interest (econometrics) as popular proprietary software. I do not deny that R is becoming more popular, but I doubt whether mailing lists and search requests are enough to prove this hypothesis.

With the command plot, I can not plot the data ND by groups (I tried it with the commands subset and groups, but ND obviously, there is no way to do so). There is always a way. I just don't understand why it is necessary to plot this as a scatterplot. Look your problem is that your data have integer values. So it is very clear that they will be overplotted and that the reader has no idea at which point are many observations even when you split the data on the x axis into groups. Or even if you make a per group plot as Baptiste suggested and as would be possible with lattice as well. I could offer an easy solution. You can split into groups manually by changing your x values slightly groupwise. But still you dont see how many data are on each point. You could add some noise with the jitter function (see ?jitter ), so that one sees that there are many observation at one point.

Re: [R] R badly lags matlab on performance?
I don't have octave (on the same machine) to compare these with. And I don't have MatLab at all. So I can't provide a comparison on that front, I'm afraid. Ted. Just to add some timings, I was running 1000 repetitions (adding up to a=1001) on a notebook with core 2 duo T7200 R 2.8.1 on Fedora 10: mean 0.10967, st.dev 0.005238 R 2.8.1 on Windows Vista: mean 0.13245, st.dev 0.00943 Octave 3.0.3 on Fedora 10: mean 0.097276, st.dev 0.0041296 Matlab 2008b on Windows Vista: 0.0626 st.dev 0.005 But I am not sure how representative this is with that very simple example. To compare Matlab speed with R a kind of benchmark suite is necessary. Like: http://www.sciviews.org/benchmark/index.html but that one is very old. I would guess that there did not change much: sometimes R is faster, sometimes not. This difference between the Windows and Linux timing is probably not really relevant: when I was comparing the timings of my usual analysis there was no difference between the two operating systems.

Re: [R] Testing predictive power of ARIMA model
for(i in 1:length(data))
{
point_data = unlist(data[i], use.names = FALSE)
x = auto.arima(point_data , max.p = 10, max.q = 10, max.P = 0, max.Q =
0, approximation = TRUE)
}
However, I would like to find a way to test the out of sample predictive
power of these models. I can think of a few ways I MIGHT be able to do this
but nothing clean. I am a recen R user and despite my best efforts (looking
on the mailing list, reading documentation) I cant figure out the best way to
do this.
if you want to test the predictive power you need a prediction. so at
least you need predict(x) in your loop and to store the predictions in
another variable. Afterwards you can calculate several measures.
another way is to use the dm.test and accuracy functions of the
forecast(ing) package which you might already have used for the auto arima.
one remark: the use of auto arima might not be the best solution since
it uses in sample fit measures (e.g. AIC) for the best in sample fit. So
for every i you might have a very different arima class. I am not sure
whether this is what you intented...

Re: [R] xyplot sorted by date
With the lattice package, I would like to plot C1 as function of C2 sorted by the dates, that is something like : xyplot(C1 ~ C2 | as.Date(C3)) It plots somethings but not the truth. I have compared the output with the output of this script I don't know whether it is ther perfect way but I did something similiar with using a factor. So you could use factors from 1:(number of days) and the dates as factor labels. But maybe there is a better way. hth Stefan ps I would be interested in truth plotting if someone has a function it could substitute parts of my reserach ;-) __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] Help With Permutations
To an adequate approximation there are 10^158 of them. Simply to obtain them all (at a rate of 10^10 per second, which is faster than the CPU frequency of most desktop computers) would take 10^148 seconds, or slightly longer than 3*(10^140) years. Current estimates of the age of the Universe are of the order of 1.5*(10^10) years, so the Universe will have to last about 2*(10^130) times as long as it has already existed, before the task could be finished. So: why do you want to do this? I want to nominate this as a fortune.
