Abstract

LOPEZ-AGUILAR, Bárbara Mariela; VILALTA-ALONSO, José Alberto; VAQUERO-PUERTA, Carlos  and  VILALTA-ALONSO, Guillermo. Statistical techniques in an alternative to support decision making with small samples: A contribution based on Bootstrap. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.203, pp.316-321. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n203.60910.

Making decisions is an important part of the work of any professional depending largely on the quality of the data and techniques used, which have limitations when the sample size is small and there is much variability in the observations. A methodology based on Bootstrap is used in the analysis of correlation between hemodynamic parameters within the aneurysmal sac and geometric indices characterizing Aneurysms of the Abdominal Aorta (AAA) by studying a sample of 13-aneurysm patients of the University hospital of Valladolid. The indices that best correlate with hemodynamics parameters are length, the eccentricity and the diameter of the iliac right. The results are very similar to those obtained by conventional methods; provide a reliable alternative to support decision-making

Keywords : Aneurysms of the abdominal aorta; statistical techniques; bootstrap; small samples..
