How to derive a confidence interval (CI) for the output of a Web22 aug. 2012 · Of course, any confidence interval would have a perfect coverage of 100% if its width were infinite—but such an interval is useless. We therefore estimate both the coverage and the width of the confidence interval for bootstrapped and classic Kriging—averaged over all v test points—in our examples. john cena shirts for sale https://plurfilms.com

The prediction data are bounded by a 95% confidence interval, which are shown as red curves in Figure 12, and we can see that almost all the observations are inside the confidence interval. Webgeostatistical tools used on this study include ordinary kriging (Matheron, 1963) and sequential Gaussian simulation (Isaaks, 1990). Sequential Gaussian simulation provides a method of assessing the uncertainty associated with the estimated velocity, which can also be approximate via ordinary kriging variance. However the later must be used with
