Guido,

Here's a quick-and-dirty solution that seems to work. it uses local macros and scalars, so it's pretty fast. I guess you'll find a way to pass the number of votes from the dataset to scalars.

however, the sequence of dividers here is "1,2,3,4,...,m"

Hope this helps,

Antoine.

----------------------------------------------------------

clear

/*fill in the number of seats and the number of parties*/

local totalseat=6

local nbparties=4

/*fill in the number of votes*/

scalar nbvp1=41000

scalar nbvp2=29000

scalar nbvp3=17000

scalar nbvp4=13000

local i=1

while `i'<=`nbparties' {

local nbs`i'=0

scalar nbv`i'=scalar(nbvp`i') /*scalars to be divided during the loop*/

local i=`i'+1

}

local string "scalar(nbv1)"

local i=2

while `i'<=`nbparties' {

local string "`string', scalar(nbv`i')" /*builds the list of votes to be compared*/

local i=`i'+1

}

local i=1

while `i'<=`totalseat' {

local j=1

local done=0

while `j'<=`nbparties' {

if scalar(nbv`j')==max(`string') & `done'==0 {

local nbs`j'=`nbs`j''+1 /*increment the number of seats*/

local done=1

scalar nbv`j'=scalar(nbvp`j')/`nbs`j'' /*divide total votes by number of seats+1*/

}

local j=`j'+1

}

local i=`i'+1

}

local i=1

while `i'<=`nbparties' {

di "Party `i' gets `nbs`i'' seats"

local i=`i'+1

}

Yep, you are quite right, Nick. Sorry, if I did not clarify this point. There is only one qualification, I would like to add to my former posting: The sequence of divisors might also be a different one, for instance, 1 - 3 - 5 (or even 1.4 - 3 - 5) for the method of (modified) Sainte Lague. In addition, I would like to preserve the initial votes that will be needed for further calculations, and the data set is rather huge (about 200 meg). As a consequence, my "brutal" slope + dummy approach took really long ...
