st: Sample selection and under-dispersed data

["Alfonso Miranda Caso Luengo" <Alfonso.Miranda-Caso-Luengo@warwick.ac.uk>]

Dear all,

A consultation. Does anyone have knowledge of a procedure for testing sample selection in a count data model with under-dispersed data? Is there any applied/theoretical paper on the topic? 

Best wishes,

Alfonso.
