PROBIT REGRESSION FOR GROUPED/CLUSTERED DATA
...K the
yearctry value would be 2000044 (having roughly 2000 observations) , and
similarly so on for the rest of the 63 countries for the year 2000 and all
other years from 2000 to 2008. For say the year 2001, the values of yearctry
for USA and UK would be 2001001 and 2001044 respectively (again 2000
obseravations for each country roughly) and so on for the other 63 countries
as well. So the data set is *grouped/clustered using "yearctry"*
I am trying to look into a selection bias if any within each "yearctry" (ie
2000 observation for one country for 9 years and so on for 65 countr...

Question:
=======
Is there a reference to the obseravation, that in R, missing parameters of
a function can be "declared" using NULL, as in
xxx <- function (x, miss=NULL) {
otherfunction <- function (x, missOther=NULL) { .. }
otherfunction(x, miss)
}
The solution of R is preferable to S+3.4's, since it allows functions

Parameter Estimation - Generalized Extreme Value Distribution
Dear R helpers,
How do you estimate the (Location, Scale, Shape) parameters of Generalized Extreme Value distribution using R?
I have tried VGAM but just not able to write the R script.
Please advise.
With regards
