question about result of loglinear analysis
...ation.The raw data is in the attachment. I fit the saturated model of loglinear with the command: glm_sat<-glm(fre~area*nation, family=poisson, data=data_Analysis) After that,I extract the coefficients: result_sat<-summary(glm_sat) result_coe<-result_sat$coefficients I find that all the coeffients are 1 or very near to 1. How does this happen?Why all the coeffients are 1 or very near to 1? Thanks!

How to display full name for the coefficients/factors in summary()?
Hi, I am wondering if there is a way to display the full anme of the regression coeffients/factors in the summary? Suppose I have a bogus data set using weekday as factor which has 7 levels such as: mydata <- sample(364) wk <- rep(1:7, 52) weekday <- factor(wk,1:7,c("Mon","Tue","Wed","Thu","Fri","Sat","Sun&quo...

R & Graphs
Dear R-users, I'm finding for a R-package concerning graphs. Is there some kind of that package? I've a set of correlation coeffients between several variable and I wish to built a graph to link variables correlated. Many thanks.

R package for bootstrapping (comparing two quadratic regression models)
...aine The two quadratic regression models are y1=a1x^2+b1x+c1 y1= observed migration distance of butterflies() y2=a2x^2+b2x+c2 y2= predicted migration distance of butterflies (based on body mass) x= body mass of butterflies null hypothesis: a1=a2 and b1=b2 and c1=c2 bootstrap to test if the coeffients (a, b, c) of the y1 and the y2 model differ [[alternative HTML version deleted]]

[mgcv][gam] Manually defining my own knots?
...it shouldn't be. Once I figure out how to do this, I'll take the fitted coefficients from each model and average them, then take the vcv's from each model and average them, and add a correction to account for within and between imputation variability, then plug them into a gamObject$coeffient and gamObject$Vp matrix, plot/summarize, and have my result. Comments welcome on whether or not this would be somehow incorrect would be welcome as well. Still have a lot to learn! Thanks, Andrew [[alternative HTML version deleted]]

Saving objects in a list and preserving attributes. How to?
...o the list, then it does build a list, but none of the elements of the list have any attributes. The list printout makes it look as though the stored items are just the text printout you get when you type "estim" on the command line, rather than an object that answers to myList[1]$coeffients or some such. -- Paul E.

Optimize parameters of ODE Problem which is solved numeric

The parameters a,b,d,e are not fix. My goal is to find the optimal parameters dependent on the error of the numerical solution compared to the registered values of PID. I would like to use instead of fix parameters, intervals. And then, through a minimizing function (minimal error) evaluate the...

bootstrapping: multilevel and multiple mediation
Hello, Have someone performed a bootstrap in a multiple-mediator model? I am trying to compute a bootstrap in a multiple and multilevel mediation. Up top now, I have developed bootstraps in random coeffient models, but I am very lost concerning the mediation. Could someone to provide me some ideas about syntax in R? Thank you very much in advance, Bea _________________________________________________________________ [[elided Hotmail spam]] [[alternative HTML version deleted]]

the significance of BEKK estimation
Dear ALL, I use BEKK package to estimate Bivariate GARCH model. But when the results come out, there's no t-stat or p-value of the estimated coeffients. Does anyone know how to get the significance? Followings are the codes I input, >P1=data.frame(x,y) >y1=mvBEKK.est(P1) >mvBEKK.diag(y1) Anyhelp would be appreciated!

Also, please kindly advise how to apply Bonferroni procedure in the test if necessary. Thank you in advance. Elaine [[alternative HTML v...
