dengue_aedes or Yoshiro--

Depending on what you actually want to do, you may find it helpful to
-expand- your data by population size (the equivalent of fweights) and
then run -locpoly- (local polynomial regression) on the expanded data.
-findit locpoly- points to the latest update (net sj 5-2 st0053_2).

Dear All,

I am thinking of using Lowess smoothing
for such a dataset in which
each data-point corresponds to one community.

Since different communities differ in
population size,
they should be weighted, as I suppose,
according to their size.

How is this possible in Stata?

Best regards.
