PROBIT REGRESSION FOR GROUPED/CLUSTERED DATA
Hello all
I have been working to fix this for weeks now, It should be simple to fix.
Please help
Let me explain what I am doing, I have a data set for 65 countries over a
period of 9 years (2000-2008). Each country has on an average say 2000
interviews, so that the total set has roughly 65*9*2000 data
points/observations (of course there are missing vales as well). Now let me
explain how are the

DECLARING A PANEL VARIABLE???

I am working on a panel data, my data are clustered/grouped by the variable

regression recognise "yearctry" as the panel variable in the regression

Heckman Selection Model/Inverse Mills Ratio
I have so far used the following command
glm(formula = s ~ age + gender + gemedu + gemhinc + es_gdppc +
imf_pop + estbbo_m, family = binomial(link = "probit"))
My question is
1. How do i discard the non significant selection variables (one out of the
seven variables above is non-significant) and calculate the Inverse Mills
Ratio of the significant variables
2. I need the inverse

GLM for Probit for Panel Data
Hello
I am working on a panel data, my panel variable is the variable "yearctry",
let me explain what I mean, yearctry is calculated based on the year and the
ISD phone code of a country, eg, for the year 2000 say and for country USA
say (code = 001), my yearctry variable will then be 2000001, there are 2000
observations (ie 2000 individual responses with yearctry = 2000001), I have

Ordered probit using clm2
Hi,
I am new in R. I would like to do a ordered probit regression using clm2 (in the ordinal package).
My dependent variable y is the way of payment in M&A: y=0 if the deal is financed by stock only, y=1 if the deal is financed by a mix of cash and stock and y=2 if it is by cash only.
My independent variables are CollateralB, Cashavailable and Leverage.
This is the code I wrote:

stata.get labels glm()
Dear R community,
I would like to import data saved with Stata and then run a Probit model using R.
My data comes from the World Values Surveys and in the Probit model I want to control for countries.
So far I figured out that I should put "convert.factors = FALSE" when using stata.get() in order to import numeric values instead of label mappings, which is what I want for most of the

How to create MULTILEVELS in a dataset??
Dear R users
I have a data set which has five variables. One depenedent variable y, and 4
Independent variables (education-level, householdincome, countrygdp and
countrygdpsquare). The first two are data corresponding to the individual
and the next two coorespond to the country to which the individual belongs
to. My data set does not make this distinction between individual level and

pseudo-additive seasonal decomposition
Dear All,
Would anyone happen to have tips on how to do a pseudo-additive seasonal decomposition in R?
I am working on a ca. 20 year monthly time series on species abundance data, with annual peaks of varying magnitude and zero abundances between the seasonal occurrences.
I have tried to use the package "x12", which utilizes x12arima, but without luck so far. More specifically, I am

How can I pick a matrix from a function? (Out Product of Gradient)
Hi all,
I would like to use optim() to estimate the equation by the log-likelihood
function and gradient function which I had written. I try to use OPG(Out
Product of Gradient) to calculate the Hessian matrix since sometime Hessian
matrix is difficult to calculate. Thus I want to pick the Gradient matrix
from the gradient function.
Moreover, could R show the process of calculation on gradient

Meaning of IR inline assembly
Hello,
Most of the IR language is correctly explained; but with inline assembly I feel alone at some point:
define i32 @main(i32 %argc, i8** %argv) #0 {
... //some uninteresting bloat here
call void asm sideeffect "outw %eax, $0", "imr,~{dirflag},~{fpsr},~{flags}"(i32 %8) #2, !srcloc !2
ret i32 0
}
I reduced the above code to the offending line containing:

Thanks, but I could not find the imr, dirflag, fpsr constraints here. Just the usual gcc/clang inline assembly constraints.
Those one were of my concern, actually :)

[HVM] Fix interrupt routing
If HVM guest Fedora 7 uses PIT and lapic timer, it can''t boot or
install.
The cause is:
At some point, Fedora 7 disables PIT interrupt by
"vioapic.redirtbl[2].mask = 1, vpic.imr.bit0 = 0 (unmasked),
vlapic.lvt[LINT0].mask = 1", and enables vlapic timer interrupt
generating;
In vmx_intr_assist() -> pt_update_irq(), we always choose IRQ0 rather

Fitting Mixture of Non-Central Student's t Distributions
Dear all,
I am attempting to model some one-dimensional data using a mixture model
of non-central Student's t distributions. However, I haven't been able
to find any R package that provides this functionality.
Could there be a way to "manipulate" the EM algorithms from the mixdist
or mixtools package to fit the model, or do you have any other
suggestions?

scan and skip - without line breaks in the input file
Dear all,
I am trying to read in big amounts of data with scan. It's only one variable, numeric values, separated by tabs,.. and it's many of them. So I was thinking that I could use the skip option and read in 100000 values at a time - but skip doesn't work, probably because I don't have line breaks in the txt file. So any value specified for skip makes the scan function jump to

Fitting Mixture of Non-Central Student's t Distributions
Dear Ingmar & Dave,
Thanks a lot for your help and sorry for the late reply.
Finally, I've found a way to separate the mixture of distributions
(empirically). But the gamlss package looks great, I'm sure it will help
me during my further studies.
Kind regards,
