✦ Synopsis

The self-contained subsets method subdivides a genetic data set into a number of subsets from which estimates are computed. The advantage of such a method is that when a subset is suspected of containing unreliable data then discarding that subset will not invalidate the remaining subsets for estimation. Thus, the complicated computation required to deal with truncated data can be avoided. In this paper, using estimation of gene frequencies as an example for one subset case, the marginal distribution of a subset total is derived and then, using this distribution, the variance of the frequency estimate of a gene frequency from the subdivision method is calculated. The subdivision method is also applied to impute the number of people of a truncated group. Finally, more complex cases where there are multiple subsets available for estimation are discussed. Results are compared to those of previous studies. Genet. Epidemiol. 14:465-477, 1997.

## Abstract Epidemiologic studies on adverse health effects of cellular telephone use have assessed exposure either by self‐reported use based on questionnaire data or by using data on subscriptions for a cellular telephone provided by network operators. With the latter approach, subjects are miscl

## Abstract Single nucleotide polymorphisms (SNPs) are important markers to investigate genetic heterogeneity of population and to perform linkage disequilibrium (LD) mapping. We propose a new method, Ψ, to express frequency of 2 haplotypes for __N~s~__ di‐allelic SNPs. Using the new expression of
