In this paper a more accurate index of asymmetry is studied. Specifically, the use of the left and right variance is proposed and an index of asymmetry based on them is introduced. Several examples demonstrate its usefulness. The question of evaluating more accurately the dispersion of data about the average emerges in all non-symmetric…

This report offers the first systematic analysis of out-of-school youth populations. In so doing, it estimates the youth bulge worldwide and measures key characteristics of out-of-school youth for sub-Saharan African (SSA) countries. In addition, as examples of how existing data can be used for analysis at the national and subnational levels, the…

The "28th Annual Report to Congress" has two volumes. Volume 1 presents a picture of how children and students are being served under the law nationwide…

The purpose of this paper is to introduce a new method for fitting item response theory models with the latent population distribution estimated from the data using splines. A spline-based density estimation system provides a flexible alternative to existing procedures that use a normal distribution, or a different functional form, for the…

The Soviet Union is experiencing substantial reduction in the growth of the working-age population, accompanied by a shift in the distribution of population growth. The government is using various means to encourage workers to move to the sparsely populated developing regions and away from the large cities. (SK)

Population shifts and settlement changes in 2 townships, Buck Prairie Township and Linn Township (near Springfield, Missouri), which are of different agricultural potential and accessibility are examined. (NQ)

A split-sample replication stopping rule for hierarchical cluster analysis is compared with the internal criterion previously found superior by Milligan and Cooper (1985) in their comparison of 30 different procedures. Situations under which the methods are equivalent or not equally useful are discussed. (SLD)
