st: IVPOIS question

["Anat (Manes) Tchetchik" <anatmanes@gmail.com>]

Dear all,
I'm still struggling with my IV Poisson model.
I'm not sure; does the assumption about conditional variance for
consistency is required ?
I read in http://www.ats.ucla.edu/stat/stata/dae/poissonreg.htm   that
the Poisson has a strong assumption; that the conditional variance
equals conditional mean
If so then what test should be used to verify if my data is
"qualified" for using this model?

Best,
