Hi Let's assume, we have a multiple linear regression, such as the one using the Scottish hills data (MASS, data(hills)): one dependent variable: time two independent var (metric): dist, climb if I am interested, after (!) fitting a lm: my. lm <- lm(time ~ dist + climb, data = hills) in the equivalence (or non-equivalence) of the two predictors "dist" and "climb": H0: dist = climb Is there any function in R, which lets me calculate this, in just giving the...

...times. However, I think I've discovered a bug. It seems that, when I use weights during an initial least-squares regression fit, and later try to add terms using stepAIC(), it uses the weights when looking to remove terms, but not when looking to add them: hills.lm <- lm(time ~ dist + climb, data = hills, weights = 1/dist2) small.hills.lm <- stepAIC(hills.lm) stepAIC(small.hills.lm, time ~ dist + climb) In the first stepAIC(), it says that the AIC for the full "time ~ dist + climb" is 94.41. Yet, during the second stepAIC, it says adding climb would produce an AIC of...

Here's the problem: I start asterisk, and it takes up around 3-4% of my CPU resources. However, this number continues to climb over the hours until it is close to 100%. Usually it takes around a day to climb up to approximately 95 or 96% Has anybody experienced the following problem before?

...appening when I was writing to a 6 TB ext4 filesystem. This was a real shocker. http://sites.google.com/site/andrewl733info/ext4_and_samba_2 On the above system (which had 6 GB of RAM), it seems that most cpu activity was restricted to a single core of a Quad Core CPU. SMBD cpu utilization climbed steadily throughout the capture. CPU began at 7 percent for one core and by the time I got to 66000 frames, I was at 100 percent cpu for one core. I started taking screen shots a third of the way through. Then I went back and started again. I also tested XFS as the filesystem. In fact, that...

Problem as follows: 1) Plug in an external USB drive. 2) Mount it anywhere. Doesn't matter how. 3) Copy a few GB of data to the drive from a non-USB disk. 4) Watch the load average "climb" to 5.x, sometimes 10.x or more. Why? This on an otherwise unloaded system. Doesn't matter how many cores, how much RAM, 32/64 bit, etc. Why should copying some files to a USB drive cause load averages to climb so high? (and network monitors to freak out?)

Dear R Community! We analyse the impact of climbing activity on cliff vegetation. During our fieldwork, we recorded 90 Transects in 3 climbing sites. The aim is to see, if the plant cover (response: Cover) is influenced only by crevice availability (predictor: Cracs), or, additional, by the distance to the climbing route (predictor: Distance). Si...

I want to extra the part of the formula not including the response variable from an lm object. For example if the lm object ABx.lm was created by the call ABx.lm <- lm( y ~ A + B + x, ...) Then ACx.lm is saved as part of a workspace. I wish to extract "~ A + B + x". Later in my code I will fit another linear model of the form z ~ A + B + x for some other response variable z. I

Hi, I've just tried upgrading from 1.1.8 to 1.2.2. As soon as the new version was started up the number of imap/pop3 processes began to climb to 800+, where I normally have about 300 or so connections at any given time. The load on the server also climbed to 150+. I've reverted back to 1.1.18, which is running just fine, but is there anything I can do to help trace what was causing the problem? Unfortunately I don't have a clue...

Can anyone help explain to me why the two codes below have different result? I thought I can use log(time)~. to replace log(time)~dist+climb+timef.I am using CVlm from DAAG package. I think nihills is preloaded with the package. Thanks in advance. > CVlm(df=nihills, form.lm=formula(log(time)~.),plotit="Observed",m=2)Analysis of Variance Table Response: log(time) Df Sum Sq Mean Sq F value Pr(>F) dist 1...

...this question has now been answered unequivocally. *** thus, i'm gonna end my discussion of on-the-fly display... i think i've been convincing in making the case for it, and people here are free to implement it or not, as they see fit. so i'll go to the next mountain for markdown to climb up. and surprise, surprise, but aaron swartz got there first. (really, i ask you, is there _anything_ this kid didn't do?) because the next mountain is back-conversion to markdown. conversion from markdown into .html is easy, easy enough that 249 people have variants of a program that can do...

...gt; the AGC does the right thing. After you speak, does the level of the > noise start going up again? > Ah, apologies, I should have mentioned that. This is against current SVN (rev 12997), built on Win32 with mingw gcc 3.4.5 using SSE. Yes, after I stop speaking, the noise slowly starts climbing again, and if I peek at st->agc_gain, that's slowly climbing too. I think part of the trouble is that the noise in here isn't uniform white noise; there's traffic outside the window and people walking in the hallway outside my door. Each little event is enough to cause the AGC...

Dear R-Help, My problem/bug came to light,when fitting a linear model using stepwise selection. I'd started with the straightfoward command step(lm(y~., dataset)) This worked fine, but because this starts with all the possible explanatory variables, it results in a model with too many explanatory variables. Hence I wanted to start with just a constant and do forward selection, to get a

Is it possible to make samba produce a log at level 10 for only a specified user(s), I am trying (still) to figure out why Samba processes climb to 100% CPU and the user loses connection with MS Word & Excel files being locked. Have been dealing with this issue for quite some time now, but had to put it on the back burner for a while because we had little time to deal with it. Apprently only an issue with a few users still, yet unable...

...telephone company to report that her telephone failed to ring when her friends called - and that on the few occasions when it did ring, her pet dog always moaned right before the phone rang. The telephone repairman proceeded to the scene, curious to see this psychic dog or senile elderly lady. He climbed a nearby telephone pole, hooked in his test set, and dialed the subscriber's house. The phone didn't ring right away, but then the dog moaned loudly and the telephone began to ring. Climbing down from the pole, the telephone repairman found: 1. The dog was tied to the telephone system...

Has anyone noticed (using the linux command 'top') a gradual increase in memory usage when asterisk is under heavy processing? I am currently pumping 4 ISDN spans (T-1) through my asterisk test system, and have seen the memory used value in top climb steadily each second. Concurrently, the value for "cached" in top also climbs, but occasionally it drops, as well. Eventually, I start eating into swap and asterisk typically starts dropping calls. A reboot is required to recover the memory, unless someone here knows of a less drast...
