fsck looping duplicate mdbox GUIDs
I have recently updated with 2.2.29.1-avh1~xenial1 ubuntu package on 16.04.
It appears that I have a couple of duplicate GUIDs which fsck can't
clear so the machine is looping through doing continuous fsck runs.
Any way to determine what the offending messages are and how to delete
or otherwise stop this?

index worker 2.3.7 undefined symbol errors (more info)
Some supplemental information:
This is happening on every email delivered into Dovecot via LMTP. The
curious things are that the message is a) successfully delivered and b)
sieved into the correct directory.
Another observation is that:
mail_deliver_ctx_get_log_var_expand_table
is defined globally in core/src/lib-lda/mail-deliver.c (and used there)

ipv4 imap not accepting connections in mixed ipv4/ipv6
I have two installations of dovecot 2.18, apart from the necessary
changes to allow them to replicate amongst themselves the configs are
identical. Both are running Ubuntu 14.04 and are kept up to date. One is
running 64bit and the other 32 bit (for historical reasons). Both have
ipv4 and ipv6 addresses.
The 64 bit installation allows access on port 143 and 993 on both ipv4

Fixed Effects using AER's Tobit function - system is singular
I have an unbalanced panel of daily, county data that is naturally bounded at
zero so my intention is to use a tobit. I'm using tobit from the AER
package. There is cyclicality in the data for each pattern that I would like
to control for before I add my variables of interest.
I run the regression:
derp <- tobit(x ~ factor(Month)*factor(County), data = data0, left = 0,
right = Inf)

Bootstrapped Tobit regression - get standard error 0...
I am trying to work out a bootstrapped Tobit regression model. I get the
coefficients all right, but they all have standard error zero. And I am
unable to figure out why. I know the coefficients are correct because that's
what I get when do a Tobit (without bootstrapping). Here's my code:

HELP: Use predict for Tobit Model. How to predict values in Tobit Model???
Hello,
I am working on a Tobit Model for a consumer good, left censored with zero.

Used standard Tobitmodel with package(AER) vor a 48 week period:

Pseudo R2 for Tobit Regression
Dear All:
I need some guidance in calculating a goodness-of-fit statistic for a Tobit
Regression model.
To develop the Tobit regression, I used the tobit() method from the AER
package, which is basically a simpler interface to the survreg() method.
I've read about pseudo R2 and C-index and was wondering if there is a
package that calculates this for me. Also, is there a reason to select

Censored (Tobit) Regression method
I need to give a quick description of Tobit Regression (TR), including how
it differs from ordinary least squares (OLS). I am an ecologist who knows
just enough about remote sensing and statistics to be dangerous in both.
Now I have found myself doing a remote sensing project where I have used TR:
survreg(Surv()). As far as I can tell, no form of Censored Regression has
been used in analyzing

Tobit variance covariance matrix
Hi,
How can I recover the variance-covariance matrix of the tobit model from
the variance-covariance of the survreg?
I first used to the survreg function and then I selected the variance
matrix. However, the last parameter is log(scale) and not the variance
of the standard deviation of the censored distribution as in the Tobit
model.

Using copulas with user-defined marginal functions
I am trying to make a loglikelihood function using copulas. I am trying to

where my mistake is?

Tobit estimation?
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 <- ystar <= 0

tobit regression model
Hi,
I'm trying to fit a tobit regression model to some data. When fitting the
exact same data in Stata, I have no problems at all, however R won't
converge. Its not a maxiters thing, since I've tried increasing this
already. I need to be able to fit the model in R since there are users of
the code that don't have a Stata license.
The code is:

predict from tobit regression
Dear R experts,
I am currently working on a rather simple tobit regression, where the
dependet variable is left-censored (>0). I would like to apply a Tobit
regression and then use the parameters of this regression to make a
prediction with new data. The intention behind this is to do an
extrapolation.
by using the VGAM or AER package, I already succeeded in getting fitted
values. However

heckit / tobit estimation
Dear All,
we (Ott Toomet and I) would like to add functions for maximum likelihood (ML)
estimations of generalized tobit models of type 2 and type 5 (*see below) in
my R package for microeconomic analysis "micEcon". So far we have called
these functions "tobit2( )" and "tobit5( )".
Are these classifications well known? How are these functions called in other

Tobit model on unbalanced panel
Appreciate any suggestions regarding how to fit an unbalanced panel data to

are unbalanced panel, including the CapEx of about 5000 properties over

Double hurdle model in R
I am interested in utilizing this so called "double hurdle" model
in my study. We can write the model in the following way:
if (z'a + u > 0 & x'b + e > 0) y = x'b + e, else y = 0
In the model, consumption y is the (left-) censored dependent variable. e
and u are the normally distributed error terms. z'a is the participation

Library & Package for Tobit regression
Hello R-Users:
I am want to use tobit regression for left censored panel/longitudinal data. Could you please provide me the name of "library" and/or "package" that will give me option of fitting tobit regression model for longitudinal data?
Thank you.
