similar to: generating random samples of IG distribution

Dear all I'm trying to caculate the MLEs for parameters of Inverse Gaussian distribution (in a k-sample problem with common mean) by using EM-Algorithm. I found some package for EM-Algorithm that are useful for missing or incomplete data and are not helpful for solving my problem. (Exactly, the problem is: Let Xij, i=1,..,k , j=1,...,ni, be a random sample from IG(?,?i). So the

Hi I have a set of data like this: *Time of Day* *Pct of Daily Volume* 9:45 7.50% 10 6.25% 10:15 4.45% 10:30 4.80% 10:45 4.45% 11:00 4.20% 11:15 2.50% 11:30 2.30% 11:45 2.25% 12:00 2.45% 12:15 2.60% 12:30 2.00% 12:45 2.05% 13:00 2.40% 13:15 1.90% 13:30 3.10% 13:45 2.90% 14:00 2.80% 14:15 2.50% 14:30 3.40% 14:45 4.40% 15:00 5.40% 15:15 4.00% 15:30 4.70% 15:45 6.20% 16:00 8.50% I want to fit

http://r.789695.n4.nabble.com/file/n3216865/Inverse_Gamma.png Hello, I am seeking help in estimating the parameters of an inverse gamma distribution (from the 'actuar' package) using a function like 'fitdistr'. Unfortunately I haven't found such a package using findFn('fit Inverse Gamma') from the 'sos' package and was therefore hoping someone might be aware

Dear all, I cannot figure out how to solve a small problem (well, not for me), surely somebody can help me in few seconds. I have a series of strings in a vector X of the type "xxx", "yyy", "zzz", "IgA", "IgG", "kkk", "IgM", "aaa". I want to substitute every ENTIRE string beginning with "Ig" with

Two questions: 1. inverse.gaussian is up there as one of the glm families, but do people ever use it? There is no inverse.gaussian in the R distribution family, and when I checked McCullagh & Nelder, it only appeared twice in the book (according to subject index), once in the table on p. 30 and once on p. 38 in a passing sentence. Is there a good reference on this distribution? 2. When I

hello all happy new year and hope you r having a good holiday. i would like to calculate the expectation of a particular random variable and would like to approximate it using a number of the functions contained in R. decided to do some experimentation on a trivial example. example ======== suppose x(i)~N(0,s2) where s2 = the variance the prior for s2 = p(s2)~IG(a,b) so the posterior is

Hi, i have one firewall/gateway server with two interfaces and a routing problem (?). eth0: external interface eth1: internal interface. Both ip address are valid. Services like DNS, HTTP is configured to run using eth1 ip address. The problem is when i try to connect from internet to firewall, i can´t see eth1 ip address... only eth0 ip address. So, when i try to connect to web

Dear R Help Please forgive my lack of knowledge,.I would be very thankful for some help. Here is my problem: I was using optim to estimate parameters of a model and I get this error message "Error in optim(x0, fn = riskll, method = "L-BFGS-B", lower = lbs, upper = ubs, : L-BFGS-B needs finite values of 'fn'" Below is the R code I have written.

Hello list. I am hoping for some help with a relatively simple problem. I have a data frame arranged as below. I want to be able to count the occurrence of each gene (eg let-7e) by Experiment. In other words how many times does a given gene crop up in the dataframe. I tried table but couldn't work out how to get the output I want. I have also considered rearranging this data into a list (by

Hello! We are a group of three students at Bielefeld University currently working on a statistical projects about neural networks. Within the framework of this project we are supposed to use the nnet-function in R and explain how it works. Since anyone of us has much experience in using R we hoped to find some information on your homepage. Unfortunatelly, we haven't been very successfull so

Hi, I have a problem using garchFit, when I use : x<-model$resid fit = garchFit(~garch(1, 1), data = x, cond.dist="dst") fit at fitted it gives me error : object "fit" not found Why it doesn't recognize fit? Thanks, Shirin

Is there a way for a domU to discover size changes of block devices modified by dom0? To make it clear - if I do in dom0 a lvresize of a logical volume given as physical disk to a domU, is there a way to use the new size of this device within the domU without reboot?
