Hi, This is the time series data collected from 2001 to 2008 by every month.so,there are 96 entries.I have done basic statistics.I need to find a model fitted to forecast this data.This is the mixedpaper collection for recycling in the campus. 13251 13754 19061 12631 17414 21350 25384 23646 20312 20740 14007 17175 13910 17191 17113 20250 35003 11975 19665 20490 20436

Hello all, I recently installed rpy2 so that I could use R through Python. However, R was not recognized in the command line. So I decided to add it to the PATH variables. But it just doesnt work.... And what I mean by it doesnt work is : No matter what I type at the prompt in DOS- be it R, Rcmd, R CMD, Rscript- it is not recognized as a command. Path variables used : 1. %R_HOME% -->

Guys, I wrote to the finance mailing list earlier with my questions but was directed here. Sorry for the repeat. --------------- library(quantmod) .... now <- Sys.time() midnight <- strptime() # <---- I want to make this a static variable that will be equal to 12:00:00 am but I dont know what to put here. I keep getting NA for everything I do if(now == midnight) {

Dear R list As suggested by Prof Brian Ripley, I have tried to read acf literature. The main problem is I am not the statistician and hence have some problem in understanding the concepts immediately. I came across one literature (http://www.stat.nus.edu.sg/~staxyc/REG32.pdf) on auto-correlation giving the methodology. As per that literature, the auto-correlation is arrived at as per following.

Hello All, Does anyone know how to download historical LIBOR rates of different currencies into R? Or if anyone knows of a website that holds all this data...I only need up to january of 2000. Also, how can we make the row names the index of a plot (the names of the x values)? [[alternative HTML version deleted]]

Hi, I have a problem with the time formatting in R. I have entered time in the format "MM:SS.xyz" and R has automatically classified this as a factor, but I need it numerically. However when I use as.numeric() it gives me totally different numbers. Is there any way I can tell R to read thes input as a number? Thank you very much [[alternative HTML version deleted]]

Hola a todos Estoy tratando de analizaruna serie temporal con datos diarios de temperaturas (40 años). He creado un objeto zoo (con ayuda de la lista, gracias) sobre el que encuentro la regresión lineal. He probado también a crear un objeto ts a partir del zoo. El problema que encuentro es que nose puede aplicar la función stl para hallar la componente estacional y la tendencia. Rdice que la

Hey everyone, I hope this finds you in good cheer. I just have a quick question: What is the function that outputs the p-value for correlation? cor(x,y) only provides the R value. I would like the p-value associated with it. Thank you all for your help! [[alternative HTML version deleted]]

i'd like to know if there is any plan or existing work to add a Aho's trig language like code generator generator? "...If you are starting a new port, we recommend that you write the instruction selector using the SelectionDAG infrastructure." any other things i should know before i write one? thank you.

As some of you know, I'm creating a hardware MDCT core. At the moment I'm working out the best way to create a lookup table for the trig values, as set up in mdct_init: /* trig lookups... */ for(i=0;i<n/4;i++){ T[i*2]=FLOAT_CONV(cos((M_PI/n)*(4*i))); T[i*2+1]=FLOAT_CONV(-sin((M_PI/n)*(4*i))); T[n2+i*2]=FLOAT_CONV(cos((M_PI/(2*n))*(2*i+1)));

We are slowly making the code generators more and more automatically generated as time goes on. The SelectionDAG infrastructure is mean to support exactly this (perform Tree or DAG pattern matching on the optimized DAG

i'd like to know what progress you guys have made (not on cvs?). i don't want to re-invent wheels, and the existing many code generator generators. i am evaluating many possbile code generation libraries. at present i give me preferrence to "Prop": http://www.cs.nyu.edu/leunga/www/prop.html and it's portable too. are there any other good library you could recommend?

Noone is currently working on automating the pattern matching generator process yet. Before doing that, there are a few changes we want to make to the SelectionDAG interface. In particular, right now, the selection process basically works like this: #1.

the proposed architecture (chris) doesn't seem to attack the phase ordering problem. through having independent instruction selection, instruction scheduling, and register allocation phases faciliate a modular design, but i believe the phase-coupled code generator generator high quality code on many architectures. espeically in the embedded system like a media/dsp processors with very limited
