simulation
I am trying to write a function that will simulate observed counts X and
Y as below, I want the function to be able give many replicates, can
somebody advise?
thanks

#alpha,n sdx and sdy are constant, and N is a vector of length n.
unstructured<-function(n,N,alpha,sdx,sdy){
Vx<-rnorm(n,mean=0,sd=sdx)
Vy<-rnorm(n,mean=0,sd=sdy)
thetax<-exp(alpha+Vx)
thetay<-exp(alpha+Vy)
X<-rpois(n,N*thetax)
Y<-rpois(n,N*thetay)
data.frame(X,Y)
}
set.seed...

help with writing function
...help will be highly appreciated.
IED<-function(risk){
n<-length(risk)
i<-c(1:n)
Diff<-numeric()
for(j in 1:n){
relrisk<-risk
relrisk[i]<-relrisk[j]
Difference<-abs(risk-relrisk)
Difference<-Difference[-c(1:j)]
Difference<-append(Diff,Difference)
return(Difference)
}

Kolmogorov-Smirnoff test
...right p-values for the comparison. Can the
Kolmogorov-Smirnoff test be adjusted for the case when ties exists and
are there any functions that already exists in R ( Kolmogorov-Smirnoff
test )performing that can be used in the case of the existance of ties?
Thank you in advance for your help.

Tried to look for package GLLMGibbs-(package for fitting mixed models by
Gibbs samppling contributed by Myles' and Clayton) in CRAN but not found
it, Does anybody know if it is still available?

Producing empirical bayes estimates in disease mapping for lognormal model
I'm trying to produce empirical bayes estimates based on the lognormal
model in disease mapping
Is there a way this can be done in R?
thanks

kernel smoothing of disease rates at locations
...ackage called fields in R (function smooth.2d)
but the problem is I get negative results after smoothing and I do not
understand why? Your contributions will be highly appreciated or if
there is any package that can do this I will be happy to know about it.
Thanks in advance for your comments.
