How do I go about building virtual population.

for example weight with respect to age and height

I wrote this package to let you do this easily:

Thank you for you response,

Sorry for asking once more. Are their published articles showing these relationships ( relationships for virtual populations based on demographic data)? I am a starter and want to understand the equations before going to the script aspect.

Thank you

Hi Shadrack, I’m a bit busy today but this video may give you a good basis to start from in that i shows you how to take an existing paper and convert to a population simulation in Phoenix.
