The Effect of Imputation on Variance Estimation, can result in an inflation in the estimator variance relative to the variance that would have occurred had all data been observed. This final appendix defines the extra variability and summarizes several methods that can be used to ensure that it properly reflected in the variance estimates.

Variance Estimation for Systematic Sampling,The method of systematic sampling, first studied by the Madows (1944), is used widely in surveys of finite populations. When properly applied, the method picks up any obvious or hidden stratification in the population and thus can be more precise than random sampling. In addition, systematic sampling is implemented easily, thus reducing costs.

Transformations,Transformations find wide areas of application in the statistical sciences. It often seems advantageous to conduct an analysis on a transformed data set rather than on the original data set. Transformations are most often motivated by the need or desire to

The Effect of Measurement Errors on Variance Estimation,We shall now introduce measurement (or response) errors and look briefly at the properties of variance estimators when the data are contaminated by such errors.
