Hi R users,

could someone help me to find out which formulas, for standard error
calculation, are  used in following example:

a=data.frame(weights=rep(c(10,1),c(4,1)),fpc=rep(41,5),uk=rep(1,5))

srs<-svydesign(id=~1, weights=~weights, data=a)

srs1<-svydesign(id=~1, weights=~weights,fpc=~fpc, data=a)

svytotal(~uk,srs)
   total SE
uk    41  9

svytotal(~uk,srs1)
  total     SE
uk    41 8.4334

and does anyone know if it is possible to find the codes for functions in
survey package?

thanks in advance

Andrija
