Abstract
CEPEDA-CUERVO, EDILBERTO et al. Confidence Intervals and Credibility Intervals for a Proportion. Rev.Colomb.Estad. [online]. 2008, vol.31, n.2, pp.211-228. ISSN 0120-1751.
Different methodologies for obtaining confidence and credibility intervals for a proportion are studied in this paper. Expected coverage, length and length variance of the interval are defined and used as a means for comparing the intervals produced by each methodology presented. These indicators were calculated using the statistical package R, used to characterize each interval; furthermore, some known properties, such as Wald intervals proportion undercoverage and Exact intervals overcoverage are verified in this study.
