Última Confidence intervals for the kappa statistic AgEcon Reichenheim, Michael E.. The command kapci calculates 100(1 - α)% confidence intervals for the kappa statistic using an analytical method in the case of dichotomous variables or bootstrap for more complex situations. For instance, kapci allows estimating CI for polychotomous variables using weighted kappa or for cases in which there are more than 2 raters/replications.

Ano: 2004 URL: http://purl.umn.edu/116269 Estimation of sensitivity and specificity arising from validity studies with incomplete designs AgEcon Reichenheim, Michael E.; Ponce de Leon, Antonio. This insert introduces valides, validesi, and validesu, a set of commands that allow the calculations of point and precision estimates of sensitivity and specificity obtained in validity studies with incomplete designs. Tipo: Journal Article Palavras-chave: Validity; Sensitivity; Specificity; Incomplete design; Research Methods/ Statistical Methods. Ano: 2002 URL: http://purl.umn.edu/116004 Two-graph receiver operating characteristic AgEcon Reichenheim, Michael E.. The command roctg allows visualizing sensitivity (Se) and specificity (Sp) curves according to the range of values of a new diagnostic test, given a “true” state of an event, the reference test. On request, several options for displaying Se and Sp estimates in, or enhancements for, the graphs are also available.
