Hi, I conduct a panel data estimation and obtain estimators for two of the coefficients beta1 and beta2. R tells me the mean and covariance of the distribution of (beta1, beta2). Now I would like to find the distribution of the quotient beta1/beta2, and one way to do it is to simulate via the joint distribution (beta1, beta2), where both beta1 and beta2 follow t distribution. How could...

The first beta of Asterisk 1.2.0 has been released! It is available from the ftp.digium.com FTP servers, as well as the Digium CVS servers (under the 'v1-2-0-beta1' tag). This version of Asterisk represents a significant improvement in features, stability and compatibility over the 1.0.x releases. Some of the major new (or upgraded) features include: * Asterisk Realtime Architecture * Asterisk Manager Interface * Asterisk Extension Langua...

...t statistics distributions (t-distr for individual coefficients, F-values for whole-model-comparisons), but instead apply a more robust approach by bootstrapping. In the simple linear regression case, one possibility is to randomly rearrange the X/Y data pairs, estimate the model and take the beta1-coefficient. Do this many many times, and so derive the null distribution for beta1. Finally compare beta1 for the observed data against this null-distribution. What I now wonder is how the situation looks like in the multiple regression case. Assume there are two predictors, X1 and X2. Is it t...

Hello, The likelihood includes two parameters to be estimated: lambda (=beta0+beta1*x) and alpha. The algorithm for the estimation is as following: 1) with alpha=0, estimate lambda (estimate beta0 and beta1 via GLM) 2) with lambda, estimate alpha via ML estimation 3) with updataed alpha, replicate 1) and 2) until alpha is converged to a value I coded 1) and 2) (it works), but fa...

Hi List, I was not able to make this work. I know it is a simple one, sorry to bother. Give me some hints pls. Thanks! Jen if(length(real.d)>=30 && length(real.b)>=30 && beta1*beta2*theta1*theta2>0 ) { r <- 1; corr <- 1; } real.d and real.b are two vectors, beta1,beta2,theta1,and theta2 are constants. The error occurred like this: Error in if (length(real.d) >= 30 && length(real.b) >= 30 && beta1 * beta2 * : missing value w...

I'm not sure which function should be used- either phyper or qhyper or dhyper Where alpha <- .75; beta1 <- 7 ; beta2 <- 5.5; etasq <- ((beta1+beta2)/(2*beta1*beta2*(1-rho))) ^2 betasq <- ((beta1-beta2)^2+4*beta1*beta2*rho)/(4*beta1^2*beta2^2*(1-rho)^2) Thank you so much for your help.

Dear All I'm attempting to speed up my model building procedure, but need some help with the loops I've created...please bear with me through the explanation! My basic model call is something like: m0sulf.nlme<-nlme(conc~beta0*exp(-beta1*day)+beta2*exp(-beta3*day), data=m0sulf, fixed=(beta0+beta1+beta2+beta3~1), random=pdDiag(beta0+beta1+beta2+beta3~1), start=c(beta0=-300,beta1=15, beta2=300,beta3=0.5), ) In ord...

hi all, I need to generate a function inside a loop: tmp is an array for (i in 1:10) { func<- func * function(beta1) dweibull(tmp[i],beta1,eta) } because then i need to integrate this function on beta. I could have written this : func<-function(beta1) prod(dweibull(tmp,beta1,eta)) (with eta and beta1 set) but it is unplottable and no integrable... i could make it a bit different but if i do that ( prod(tm...

Hmm, this is peculiar! This mailbox has been unchanged on my test server since September. I've been using it to test each new version of Dovecot just after I've compiled it. When beta1 was released, I opened this mbox with no problems. However, when I upgraded to beta2, I got "file size unexpectedly shrinked in mbox file /export/mail/a/24/vis99003/INBOX (16895967 vs 16899267)". Reverting to beta1, it also failed with the same error! I've deleted indexes, restored t...
