hello, I have a question about making n step ahead forecasts in cases where test and validation sets are availiable. For instance, I would like to make one step ahead forecasts on the WWWusage data so I hold out the last 10 observations as the validation set and fit an ARIMA model on the first 90 observations. I then use a for loop to sequentiall...

Dear colleagues, ?arima? returns directly the 1-step ahead errors but I am interested in obtaining other h-step ahead errors for several ARIMA models I have fitted. Is there any way I can obtain this with R? Any help would be appreciated. Sincerely, Nuno Prista _________________________ CO - FCUL, Lisboa, Portugal CQFE - ODU, Norfolk, USA

I've been having a problem with motion on one server - the .avi's it produces are dark, low contrast, and it keeps resizing from 642x420 to 296x360 or some such. Trying to figure it out, I was just going through /var/log/dmesg, and found rtc0: alarms up to one year, y3k, 114 bytes nvram I mean, y3k? I think we've got 900 years or so to worry 'bout that.... mark

..., >Jan97=1*(seq(airmiles)==13),Dec02=1*(seq(airmiles)==84)),method='ML') Ok,so I've run the above code and an object called air.ml has now been created of class type arimax.According to the documentation this is the same type as arima.So now I make a prediction,say 15 time steps ahead: >forecast=predict(air.m1, n.ahead=15) The following error is produced: Error in predict.Arima(air.m1, n.ahead = 15) : 'xreg' and 'newxreg' have different numbers of columns -------------------------------------------------------------------------------------------...

Hello, Thank you for your help/advice! The issue here is speed/efficiency. I can do what I want, but its really slow. The goal is to have the ability to do calculations on my data and have it adjusted for look-ahead. I see two ways to do this: (I'm open to more ideas. My terminology: Unadjusted = values not adjusted for look-ahead bias; adjusted = values adjusted for look-ahead bias.) 1) I could a) do calculations on unadjusted values then b) adjust the resulting values for look-ahead bias. Here is what I...

hello, i was trying to predict values for a garch, so i did: predict(fitgarch,n.ahead = 20) but this doesn't work. Someone can tell me how to get the 20 values ahead of a garch model. thanks in advance _________________________________________________________________ O Windows Live ajuda-o a manter-se em contacto com todos os seus amigos, num só local. http://www.microso...

Your clock is an entire day ahead of your cell phone, unless you're emailing us from the future. If you are emailing from the future, is it like the Jetsons? Are there flying cars?

By the way, on a slightly related note, I'm pretty sure either parallel-readdir or readdir-ahead has a regression in GlusterFS 3.12.x. We are running CentOS 7 with kernel-3.10.0-693.11.6.el7.x86_6. I updated my servers and clients to 3.12.4 and enabled these two options after reading about them in the 3.10.0 and 3.11.0 release notes. In the days after enabling these two options all of my clie...

Hi Is there a way to tweak the read-ahead settings via the gluster command line? For example: gluster volume set somevolumename performance.read-ahead 2 Or is this no longer feasible? With read-ahead set to the default of 8 like was the case with standard volgen generated configs, the amount of useless reads happening to the bricks is...

Hi, I am trying to educate myself on prefetching/readahead algorithm for Lustre''s read. For a starter I only have two simple questions. 1 - Does Lustre detect linear or random I/O pattern or it always triggers readahead? 2 - If readahead is triggered, how many pages are read in addition to what is necessary? Thanks, Arifa.

...is again on my system just yet! It caused too much instability for my users and I don't have enough resources for a development environment. The only other variables that changed before the crashes was the group metadata-cache[0], which I enabled the same day as the parallel-readdir and readdir-ahead options: $ gluster volume set homes group metadata-cache I'm hoping Atin or Poornima can shed some light and squash this bug.

Please don't shoot me for cross posting, but I wanted to share this with everyone. Just thought you'd like to know that I've discovered a very interesting thing about AIX and Samba with respect to Sequential Read Ahead. I had been tracking a number of issues related to performance on my Samba 2.2.7a server and didn't have any issues other than lengthy profiles when I was running 4.3.3. Now that I'm at 5.1, the 32-bit and 64-bit kernel seem to do a *lot* of thinking about the history of your reading. Wh...
