Title: Independence of Duplicate and Invalid Signatures on a Petition
Author(s): Mary Whiteside*+ and Mark Eakin
Companies: University of Texas at Arlington and University of Texas at Arlington
Address: Box 19437, Arlington, TX, 76019,
Keywords: Nonlinear ; Goodman ; Petition signatures
Abstract:

This paper investigates the assumption that replicated signatures and signatures that are invalid for other reasons are independent. This would mean that the proportion of replicated signatures is the same for valid and invalid signatures. In this case, a non-linear estimate for the total number of valid signatures on a petition has been shown to be superior to the traditional Goodman estimate.
