Dear R users, I am using plm packege in R to build my model, but from the result I can't quite figure out what it is... Can anyone tell me why? Am I missing something? R Results: *> ar1<-plm(formula=ADOP~lag(ADOP,1)+PE+WOR, + data=well, effect="time",model="within") > summary(ar1)* Oneway (time) effect Within Model Call: plm(formula = ADOP ~ lag(ADOP, 1) + PE

Hello, I have two time series objects, 1 is yearly (population) and the other is quarterly (bankruptcy statistics). I would like to produce a quarterly time series object that consists of bankruptcy/population. Is there a pre-built function to intelligently divide these time series: br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2)) distPop.ts = ts(data=distPop.df[,-1],

Dear all, i just wonder if there´s a way to use a two column time index field in plm package. the manual says the following concerning data indexing: a character vector of length two containing the names of the individual and the time index, What would y´all do with a quarterly dataset that contains one column for the period and one for the year. Do I have to convert it to one single date

hello, Suppose you a monthly series you want to aggregate at a quaterly frequency with the start and the end of your series in the middle of the quarter. For example 2001M2 2001M3 2001M4 2001M5 2001M6 2001M7 12 13 12 14 16 15 how can you get something like : 2001Q1 2001Q2 200Q3 NA 14 NA or 2001Q1 2001Q2 200Q3 12.5 14 15 Thanks in advance

Hi, I've just upgraded to wine-20010905 (from wine-200103??) and the new versions gives me an error message when I start a dictionary program: Error message: Acces violation at address 780B751F in module 'shdocvw.dll'. Write of address 00000098. Can anyone give me a hint how to get around this bug? Thanks.

Hi, I am new to use R, but can anyone tell me how to tranform quarterly data to monthly data? I know SAS has this procedure, so may I assume it is also available in R? Thanks a lot! Ed

Dear all, Does anyone know if the PLM package (to run Panel Data Analysis) accepts quarterly data? The package vignette and documentation only use annual data -and the only time index available seems to work for years.

Hi, I was wondering if there is a package I can use to convert my 22 annual observations to quarterly time series so that I will have 88 observations. Also, will there be any harm in doing so? will I loose any important data specific info? I want to run VARs in levels using TY method. Due to small sample, i will probably use a bootstrap method. Thanks! [[alternative HTML version deleted]]

I have time series observation on daily frequencies : library(zoo) SD=1 date1 = seq(as.Date("01/01/01", format = "%m/%d/%y"), as.Date("12/31/02", format = "%m/%d/%y"), by = 1) len1 = length(date1); data1 = zoo(matrix(rnorm(len1, mean=0, sd=SD*0.5), nrow = len1),  date1) plot(data1) Now I want to calculate 1. Quarterly statistics like mean, variance etc

I have a data set with quarterly time series for several variables. The time index is recorded in column 1 of the dataframe as a character vector "Q1 1961", "Q2 1961","Q3 1961", "Q4 1961", "Q1 1962", etc. I want to produce line plots with ggplot2, but it seems I need to convert the time index from character to date class. Is that right? If so, how

Using Achim's d this also works to generate z where FUN is a function used to transform the index column and format is also passed to FUN. z <- read.zoo(d, index = "time", FUN = as.yearqtr, format = "Q%q %Y") On Sun, Jan 28, 2018 at 4:53 PM, Achim Zeileis <Achim.Zeileis at uibk.ac.at> wrote: > On Sun, 28 Jan 2018, phil at philipsmith.ca wrote: > >> I

Dear R users, I have a dataframe where column is has countries, column 2 is dates (monthly) for each countrly, the next 10 columns are my factors where I have measurements for each country and for each date. I have attached a sample of the data in csv format with the data for 3 countries. I would like to convert my monthly data into quarterly data, finding the mean over 3 month periods for

I am a game developer, and we used RC3 in our last game. Worked great. I'm trying to update to 1.0 now, and running into some problems. Specifically, I think a change to _get_prev_page() in vorbisfile.c broke the decoder for very small files. I have a file called "silence" that's just a silent wav file. It compresses down to barely more than the header, so it's _really_

Hi. I'm trying to get a list of the channels currently in use on an Asterisk server (1.8.32.1 if it matters) over AMI. I send the command "sip show channels", and I get back a response along the lines of (* used to protect the innocent...): Peer User/ANR Call ID Format Hold Last Message Expiry Peer *8.22.*0.34 02035644444

Dear Gavin, This is really great, thank you! I created some long loops to get rid of extra months at the beginning and the end of my data but your code is great for putting it then together quarterly. thanks again, Denise On Mon, 2008-08-18 at 14:31 +0100, Denise Xifara wrote: > Thank you very much Stephen, but how will aggregate deal with months that > fall outside annual quarters? eg,

I'm currently adding multi channel playback support to my DirectShow Ogg/Vorbis filters and looking for a place to store the channel mapping. Are there already specs how and where to store it. There was already a suggestion 8 months ago (http://www.xiph.org/archives/vorbis-dev/200107/0026.html) to store it in a tag but the answer was that it should go into header. Is there any new about this?

Hello, I have a few questions about the block size in ogg vorbis 1. The allowed blocksizes are powers of two between 64 and 8192 Samples. As I understood , there are fixed sizes for long and short blocks . The encoder can pick any allowed value for long blocks and onother value, that must be smaller or equal to the first one, for short blocks. On which base does the encoder choose the size for
