Hi, Given that R reports Type I sums of squares, isn't it a bit anachronistic that it re-orders terms in formulae? > d <- expand.grid(y=rnorm(8), + A=factor(c(1,2)), + B=factor(c(1,2)), + C=factor(c(1,2))) > summary(aov(y ~ A+B+A:B+C,data=d)) Df Sum Sq Mean Sq F value Pr(>F) A 1 8.294e-34 8.294e-34 1.027e-33 1

Hello, I'm writng this message to see if anyone knows how to analyze a data with geometrically distributed outcome. My situation now is : I have a outcome which is geometrically distributed. And I've also self-derived the link function for geometric distribution. I want to use generalized linear models to analyze it, but there're only models for binary data, poisson distributed

Hi I am performing an analysis of variance with two factors, each with two levels. I have differing numbers of observations in each of the four combinations, but all four combinations *are* present (2 of the factor combinations have 3 observations, 1 has 4 and 1 has 5) I have used both anova(aov(...)) and anova(lm(...)) in R and it gave the same result - as expected. I then plugged this into

Dear Rich, It depends how the data is generated. Although I am not an expert in ecology, I can explain it based on a biomedical example. Certain variables are generated geometrically (exponentially), e.g. MIC or Titer. MIC = Minimum Inhibitory Concentration for bacterial resistance Titer = dilution which still has an effect, e.g. serially diluting blood samples; Obviously, diluting the

Dear all, I would like to know which is the right way to check the normality assumption for performing ANOVA. How do you check normality for the following example? I did an experiment where people had to evaluate on a 7 point scale, the degree of realism of some stimuli presented in 2 conditions. The problem is that if I check normality with the Shapiro test I get that the data are not

I am looking to build a small PBX for an office that has 3 incoming analog lines and less than 10 extensions. For the Asterisk server I am going to use a small form factor PC with no-PCI slots so the FXO interface needs to be either FXO->SIP or USB. Can anyone make suggestions? I am looking at an AudioCodes MP114 FXO or possibly two Sangoma U100's but don't have experience with

I receieved my first PAP2-NA yesterday from our distributor(Tech Data). It installed pretty easily and has worked great so I went to order some more of these units today. When I logged into Tech Data this morning, the PAP2-NA was now marked as discontinued and no longer available and only the PAP2 version was available which is the Vonage branded version. :( I saw someone on the list say that

I am having a problem with a new PRI turn-up on dahdi 2.5.0 and asterisk 1.8.5 that I have not seen before. The PRI is setup as B8ZS, ESF and the span shows up and ok. This PRI is merely a crossover T1 going into an old DC0 class 5 switch. I am getting the following errors over and over again [Aug 16 10:26:10] NOTICE[8002]: chan_dahdi.c:3043 my_handle_dchan_exception: PRI got event: HDLC Bad FCS

Hello, I am trying to get the output from the numerical simulation of a system of ordinary differential equations for a range of values for three parameters. I am using the ode() function (deSolve package) to run the numerical simulation and apply() to run the simulation function for each set of parameter values. I am having trouble getting the apply() function to work. Here is an

I'm a bit of a samba newbie, but I've googled all morning for an answer before posing this question. I'm using winbind to authenticate telnet user logins against my PDC. (Yes, I know - I'll be switching to ssh shortly :-) Anyways, I was wondering if there is a way to eliminate the need to enter the domain as part of the user name when logging in. We only have one domain, and

I want to write a function to take an argument as the response variable of a linear model, e.g. to do anova's across a list of variables, something like the following (except, of course, this doesn't work): function(x) { anova(lm(x ~ my.factor,data=my.data)) } The x in lm() above is getting evaluated at the wrong level. How can I make this work? -- Russell Senior ``The two

To anyone who can help: I am trying to do an analysis of variance with a very unbalanced design and a few empty cells. How do I get R to use type III and more importantly type IV sums of squares? Thanks Deven Hamilton Department of Sociology University of Washington

Hi R-people, I am wanting to run Factorial ANOVA followed by Scheffe tests on some spatial subjective data. I'm comparing X-Y independent coordinates against x-y dependent coordinates. There are only four independent spatial coordinates that form a square. I am wondering whether I am doing the right thing, because there doesn't seem to be a simple way of doing this. I have attempted to

Hello, Today I updated one of our computers running CentOS 5.3 32bit. After a reboot I notice the following with lsof -i sshd 3638 root 3u IPv6 17317 TCP pc46.astro.up.pt:ssh->119.1.193.205:zephyr-clt (ESTABLISHED) sshd 3639 sshd 3u IPv6 17317 TCP pc46.astro.up.pt:ssh->119.1.193.205:zephyr-clt (ESTABLISHED) What is this connection?

I have 20 variables: 5,9,6,1,5,9,7,4,5,6,3,2,4,8,9,6,1,8,4,8 How do I calculate the corresponding quantiles from a normal distribution with the same mean and variance as the sample? Also, how do I draw a QQ plot of the data?

R-lings, I know the algo for Laplace generation, but arent there any packages available. Also, i'm trying to check for the Bernoulli sums obey the CLT, but though i calculate 2000 values of S(n)-n*p ---------- sqrt(n*p*(1-p)) for p=.5 and n=45, this fails both KS test and shapiro test. Why?? Thanks sapsi ISI,Delhi please reply to sapsi at bigfoot.com

Hello, after searching through the archives and not finding a thread that answers this question, I thought I'd pass it on to the list. Given a data frame and given a factor variable that assigns a class to each case in the data frame, what is the most efficient way to sample a given number of cases from each class? I've found a roundabout solution that works as follows: for each class:

Hello As a postgrad I have been helping an undergraduate student with R coding but she has a problem with R studio on her laptop which I can't fix - basically when she runs a plot it appears without a y axis label with the black line plot frame hard against the plot window and the bottom of the plot, where you would expect to see the horizontal axis and the x axis label etc is completely

Dear All I am totally new to R and I would like to know whether R is able and appropriate to illustrate to my students the Central Limit Theorem, using for instance 100 independent variables with uniform distribution and showing that their sum is a variable with an approximated normal distribution. Thanks in advance, Paul
