Re: st: drawnorm for discrete variables

[Tyler Frazier <tyfrazier@gmail.com>]

Hi, thank you for your response and observations.

I am looking for a relatively simple answer, which I plan to improve
upon in time.

The data will be used in an urban simulation which incorporates a
number of location choice models, regression, and other simple models.
 For now I would like to establish a method for synthetically
generating the data, for use in the larger spatial, framework.  At
this point, I am seeking a plausible solution for running the urban
simulation in order to observe its behavior.

I want to generate a population of approximately 200,000
persons/households. Ideally, the persons/households datasets for this
african city would have the following variables (see below).

As indicated, some of these variable are continuous (income), while
others are categorical (tribal affiliation) or binary (sex)

the survey itself is a fairly large sample, with about 3500 persons in
approximately 1100 households, for the applicable metropolitan area.
there is also a question of how to iteratively sample household and
person data

Any suggestions on the direction I should take are greatly appreciated.

Best regards,
Ty
