Newson R, 2005, Efficient Calculation of Jackknife Confidence Intervals for Rank Statistics, Vol: 15

An algorithm is presented for calculating concordance-discordance totals in a time of order N log N , where N is the number of observations, using a balanced binary search tree. These totals can be used to calculate jackknife estimates and confidence limits in the same time order for a very wide range of rank statistics, including Kendall's tau, Somers' D, Harrell's c, the area under the receiver operating characteristic (ROC) curve, the Gini coefficient, and the parameters underlying the sign and rank-sum tests. A Stata package is introduced for calculating confidence intervals for these rank statistics using this algorithm, which has been implemented in the Mata compilable matrix programming language supplied with Stata.

The ideal videoconferencing environment would produce the minimum feeling of artificiality for its users. We assessed nurse and patient perceptions of artificiality by varying the technical and operational procedures for telemedicine in a minor injuries unit. Twenty-five patients and eight emergency nurse practitioners (ENPs) participated in simulated teleconsultations under a variety of different conditions and completed a Likert-scale survey. There was a close correlation between the ENPs' ratings and the patients' ratings for the various factors (r > 0.99). In relation to technical factors, a flicker-free television screen and the user being seated close to the screen were preferred. Similarly, in relation to operational procedures, an initial explanation of telemedicine, introductions and adequate preparation were also preferred. The study suggests that careful attention to technical specifications and operational procedures can reduce the perceived artificiality of teleconsultations.
