ABSTRACT
The jackknife procedure involves the use of a single random sample of data drawn from a population of data. Recall that the sample statistic is an estimate of the population parameter. We also learned in previous chapters that how good the sample statistic is as an estimate of the population parameter depends on the sample size. The jackknife procedure is concerned with whether the sample statistic as an estimate of the population parameter is affected by any single data value. For example, we know that the sample mean is affected by extreme data values, which is indicated by the standard deviation of the sample data.
