Need an advise for bayesian estimate
...ce reported a quite different estimates
for the follwoing ethylene data applying bayes method using MCSIM. As seen
below glm give same results regardless of response data format, i.e.,
two-column or binary formats, but bayesglm would give different results.
The result from French report is -91.78+8*lnC+6.055*lnT which lie
between prior.df=1 and 2 appling binary data format in R.
My question are as follows:
1. What is advantage using bayes estimate? Is it better for small samples?
2. How to resolve different estimates depending on the format of response
data, and the prior specs (Ex: prior.df)?...

question about the degrees of freedom
...ral 2-digit industry codes that i want to use for conducting by-industry analysis but i think there is a problem with the degrees of freedom!
for example, when i do my analysis without any 2-digit industry code, i got the following summary (i have 146574 observations in total):
> abc<-lm(lnQ~lnC+lnM+lnL+lnE+eco+inno, data=ds)
> summary(abc)
Call:
lm(formula = lnQ ~ lnC + lnM + lnL + lnE + eco + inno, data = ds)
Residuals:

question about the degrees of freedom
...ffect of the independent variables on the 11th industry i defined a dummy variable such as:
ind=(ind_2d==11)# this supposed to mean, ind is equal to 11th industry in other words just take into account the firms which has the code 11, am i mistaken here?

equivalent of stata command in R
...ed, 9 Jun 2010 09:53:20 +0000
OK! sorry thats my fault,
here the translations of the stata commands
1st step is to get the mean values of the variables, well that doesnt need explanation i guess,
2nd step is to estimate the model on panel data estimation method
which is:
mdl<-plm(lnLP~lnC+lnL+lnM+lnE+Eco+Inno+Eco*Inno+Eco*lnM+Eco*lnE+year,data=newdata,model="within")
and basically i need to get the marginal effect of variable "Eco" at the sample mean (step 3) but i am not that good in R so any additional help is wlcome!
Thanks

plm package duplication problem

this command works just fine, i can even get the summary of "dsn" with
>summary(dsn) which works fine also, however my problem starts when i define
my model and i cant find where do i make mistake!!
i try to create my model with the following command
>dsn.plm <- plm(lnQ~lnC+lnL+lnM+lnE,data=ds,
random.method="walhus",effect="twoways",model="random")
and than i get this error message
duplicate couples (time-id)

System hangs up every day
Hello everybody
Unfortunately my problem still doesn't have any solution.
But I have an interesting observation. The gateway freezes very quickly, if torrent client programs are running on workstations.
I assume the cause of the problem consists in many number of TCP/IP connections that torrent client establishes.
Any ideas?
Maybe I can tune somehow a TCP/IP via kernel, sysctl or pf settings?

in FPGA. When I had a chat with Leonardo we were thinking in rewrite these
