| Hence, the unbiased variance estimator may be negatively biased due to spatial autocorrelation. |
| Further work might include the more accurate estimation of distribution of our estimator, using bootstrap or jackknife techniques. |
| Whereas estimator surrogates, they argue, are subject to empirical justification, true surrogates are still dependent on convention. |
| This is based on an analytical relationship between the expected value of the estimator and its real value. |
| Thus, for this situation, the estimator can be thought of as an upper bound of the venue-based population size. |
| In contrast, the likelihood estimator maintains a low standard error across the full range of conditions. |
