variance estimator with g=2 (i.e., 2 replications) is shown to be less than the TSL variance estimator. In an evaluation study using seventeen natural populations, Rao and Kuzik (1974) found that the stability of the jackknife variance estimator (with g=n) to be comparable to that of the TSL variance estimator.

For example, the fourth variance replicate estimate is named Var_Rep4. For the majority of ACS estimates, these values are used to form the variance of the estimate. The formula is provided in the next section.

It turns out, however, that S 2 is always an unbiased estimator of σ 2, that is, for any model, not just the normal model. (You'll be asked to show this in the homework.)

Conclusions Figure 2, 4, and 5 show that, in case of small population size, the Jackknife variance estimator for two samples has less standard deviation (variation) than Jackknife variance estimator for one sample.
