Defining multiple variables in a loop
Good day,
For lack of a better solution (or perhaps I am ignorant to something
more elegant), I have been bootstrapping panel data by hand so to
speak and I would like to know if there is a way to define multiple
variables in a loop using the loop variable. I found a post (here:
https://stat.ethz.ch/pipermail/r-help/2002-October/026305.html ) that
discussed naming multiple variables but it

ivreg with fixed effect in R?
I want to estimate the following fixed effect model:
y_i,t = alpha_i + beta_1 x1_t + beta_2 x2_i,tx2_i,t = gamma_i + gamma_1
x1_t + gamma_2 Z1_i + gamma_3 Z2_i
I can use ivreg from AER to do the iv regression.
fm <- ivreg(y_i,t ~ x1_t + x2_i,t | x1_t + Z1_i + Z2_i,
data = DataSet)
But, I'm not sure how can I add the fixed effects.
Thanks!

instrumental variables regression using ivreg (AER) or tsls (sem)
Dear friends,
I am trying to understand and implement instrumental variables
regression using R.
I found a small (simple) example here which purportedly illustrates the
mechanics (using 2-stage least-squares):

Basically, here are the R commands (reproducible example) from that

A fast version of ccf () accepting missing values ?
Dear R-Helpers,
I need to compute cross-correlation on two signals wich may contain
missing values.
One cannot pass "Na.action=na.pass" to the ccf() function.
So, I wrote a naive function of my own (see below).
Unsurprisingly, this function is not very fast.
Do you think that it is possible to do better, or should I accept my fate
?
Bruno.

Potential cross-platform package building issue
I am using 32-bit R 3.1.2 on Windows 7.
I recently conducted an `R CMD check --as-cran` on a recently-developed
package and received only the 'New submission' note. Research on
StackOverflow and on R-devel suggested this could be ignored. I also used
devtools::build_win() and received no notes or warnings, other than the one
mentioned previously. Lastly, I conducted an `R CMD check` with

2SLS with Fixed Effects and Control Variables
Dear John Fox, Christian Kleiber, and Achim Zeileis,
I am attempting to run various independent variable parameters to assess
their suitability. Unfortunately, I hit a snag and couldn't get the tests
to run properly. When I used ivreg, I got an error message saying: "Error
in eval(predvars, data, env) : object 'WageInequality' not found."
Can you please help?

2SLS with Fixed Effects and Control Variables
Kelis,
thanks for your interest. It's hard to say what exactly goes wrong based
on the information you provide. However, I would recommend that you first
process the data:
- Store all variables as the appropriate types (numeric, factor, etc.)
in the data frame. Then you don't have to put these things into the model
formula.
- Employ variable names without spaces, then you don't

Instrumental Variables Regression
Hi there,
I hope to build a model Y ~ X1 + X2 + X3 + X4 with X1 has two
instrumental variable A and B, and X2 has one instrumental variable A. I
have searched the R site and mailling list, and known that the tsls()
from sem package and ivreg() from AER package can deal with instrumental
variable regression, however, I don't know how to formula the model.
Any suggestion will be really

How to do poisson distribution test like this?
Dear R-listers,
I want to reperfrom a poisson distribution test that presented in a
recent-published biological research paper (Plant Physiology 2008, vol 148,
pp. 1189-1200). That test is about the occurrence number of a kind of gene
in separate chromosomes.
For instance:
The observed gene number in chromosome A is 36.
The expected gene number in chromosome A is 30.

lmer: Interpreting random effects contrasts and model formulation
I'm trying to fit a nested mixed model using lmer and have some
questions about the output and my model formulations.
I have replicate measures on Lines which are strictly nested within
Populations.

Populations are fixed and the random Line effect is constant across
Populations, I have:

Confidence intervals for the Instrumental Variable estimators of TWO causal effects
Dear all,
I am using the Instrumental Variable approach to estimate the causal
effects of TWO endogenous variables in a Mendelian Randomization study.
As long as point estimation is concerned, I have no problem: both "ivreg"
in library "AER" and "tsls" in library "sem" do the job perfectly. The
problems begin

Sometimes commands do not terminate after upgrading to R 4.0 and Ubuntu 20.04
I have upgraded R (from 3.6 to 4.0) and RStudio (from 1.1 to 1.2.5) a few
days ago, and Ubuntu from 18.04 to 20.04 yesterday.
Since then, R sometimes never terminates when executing certain commands:
ivreg (from package AER), summary (of a logit regression) and logitmfx
(from package mfx). Sometimes these commands run fine, but most of the time
I have to kill the process because R won't

Again on Data Mining
Dear All,
I have already posted before on the list about data mining and it has
proved very useful.
I have now a training dataset consisting of N objects of M<<N different
kinds (actually, M is usually 3 to 5, whereas N is of the order of 1000).
Every object has its own label L_i, i=1...N, that is known.
For each of these objects I measure some property in time (let's say I

question about 2SLS
Hi All,
I am using R 2.11.0 on a Ubuntu machine. I estimated a model using "tsls"
from the package "sem". Is there a way to get Newey West standard errors for
the parameter estimates?
When estimating the model by OLS, I used "NeweyWest" from the package
"sandwich" to get HAC standard errors. But, I am not able to use the same
method with the results of the
