Folks, Based on http://www.biostat.wustl.edu/archives/html/s-news/1999-06/msg00125.html I thought I should experiment with using survreg() to estimate tobit models. I start by simulating a data frame with 100 observations from a tobit model > x1 <- runif(100) > x2 <- runif(100)*3 > ystar <- 2 + 3*x1 - 4*x2 + rnorm(100)*2 > y <- ystar > censored <-...

Having read previous correspondance on this topic, am I right in using a gaussian distribution for a tobit model, one article suggests a normal distribution? Also, I want to censure at the upper bound, so, using the survival5 package I use: survreg(Surv(y,y<c,type="right")~x) for a censored regression. Could anybody who's had experience of this, confirm whether I'm in the

Hello there, In OpenSSH 3.0.2p1 there is a strange name resolving bug: /etc/nsswitch.conf shows: hosts: files dns When I am trying to connect to a host that is in /etc/hosts using the hostname, ssh tries to first resolve this name using the dns, regardless to the resolve order in /etc/nsswitch.conf, if the dns is timeout or the machine is not connected to the Internet at this time -
