... but do note: glm(lot1 ~ log(u), data = clotting, family = gaussian) is a plain old *linear model*, which is of course a specific type of glm, but not one that requires the machinery of glm() to fit. That is, the above is exactly the same as: lm(lot1 ~ log(u), data = clotting) and gives exactly the same sigma() ! (and I would therefore hazar...

Hi, I have below GLM fit clotting <- data.frame( u = c(5,10,15,20,30,40,60,80,100), lot1 = c(118,58,42,35,27,25,21,19,18), lot2 = c(69,35,26,21,18,16,13,12,12)) summary(glm(lot1 ~ log(u), data = clotting, family = gaussian)) Is there any direct function to extract estimate of Error standard deviation?

Dear expRts, when I try to build a package by myself, the process fails writing the following messages to 00install.out: * Installing *source* package 'dynalc' ... ** libs WARNING: no source files found chmod: Zugriff auf ?/home/hannes/texte/forschung/clot/programme/dynalc.Rcheck/dynalc/libs/*? nicht m?glich: No such file or directory ** R ** data ** inst ** help Note: removing empty

...xpecting. The y-axis of the plots is tau and I would like that axis to be the likelihood so that I have a curve that maxes at the parameter estimate. I am not sure where I find those likelihood values? I may just be misinterpreting the theory behind this. Thanks for any help you can give.

Hi R users, I want to use dglm Package. I run the examples and it give me an error: Error en dglm(lot1 ~ log(u), ~1, data = clotting, family = Gamma) : no se pudo encontrar la funci?n "as.family" dglm can't find "as.family" function why ? Thank you for your help

I am trying to plot the results of a random effects model where each subject is allowed to have his, or her, own intercept. I use xyplot to plot the data, lme to compute the regression and then try to put a summary regression line on the xyplot. As can be seen by the output pasted below, I am getting an error message, Error in int_abline(a = a, b = b, h = h, v = v, untf = untf, ...) : (list)

Hi, I have a data set (weight) that does not follow the Gaussian (Normal) distribution. However, I have to transform the data before applying the Gaussian distribution. I used this syntax and used log(weight) as: posJy.model<-glm(log(weight) ~ factor(pos), family=gaussian(link='identity'), subset=Soil=="Jy"). This syntax COULD NOT transform the data. But if I transform the

Anyone conceive of any reason why I should have a stream that RealPlayer and iTunes have no problem with, but MP9 refuses to play: just sits there dumbly having loaded the .m3u that points to it, ignoring the play button?

I am experiencing a curious event, and wondering if others have seen this... As well, I have a question related to it. Today, I noticed my puppet summary report from Foreman this morning, that 60 of my 160 hosts all stopped reporting at nearly the exact same time, and have not since restarted. Investigating, it appears that my puppetmaster temporarily ran out of disk space on the /var
