This comment offers three descriptions of "p[subscript rep]" that start with a frequentist account of confidence intervals, draw on R. A. Fisher's fiducial argument, and do not make Bayesian assumptions. Links are described among "p[subscript rep]," "p" values, and the probability a confidence interval will capture…

Meehl's taxometric method was developed to distinguish categorical and continuous constructs. However, taxometric output can be difficult to interpret because expected results for realistic data conditions and differing procedural implementations have not been derived analytically or studied through rigorous simulations. By applying bootstrap…

In many evaluations, presenting probability distributions of cost-effectiveness results offers a convenient way to show the likelihood of various conclusions given the uncertainties in the inputs. The techniques presented in this paper should be useful for many programs characterized by controversy over perspectives, assumptions, and dollar…

Nonparametric and robust statistics (those using trimmed means and Winsorized variances) were compared for their ability to detect treatment effects in the two-sample case. The use of two specialized tests, designed to be sensitive to treatment effects when data distributions are skewed to the right, is not supported by the analyses. (SLD)

A procedure for the analysis of judgmental estimates is derived. It uses a t-distribution concept to derive the relative experience of an expert and uses the derived experience as weight to obtain a weighted mean. Using this method, error in estimation was reduced by an average of one-half. (Author/BW)

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

In this study four research strategies used in previous studies of the socialization of cognitive skills were first contrasted and then assessed in terms of five criteria. (The data base for this study was 32 videotapes of mothers preparing their 7- or 9-year-old children to take a memory test.) The four strategies (frequency coding, fine-grained…

Refines the cohort survival method for projecting student enrollment. Tests its effectiveness with 30 Maine school districts. The refinement empirically searches for optimal values of number of years of history to use in averaging, weights to place on the ratios, and linear versus exponential distribution of weights across ratios.

The combined field tests for the third follow-up survey of High School and Beyond (HSB) and the fifth follow-up survey of the National Longitudinal Study of the High School Class of 1972 (NLS-72) were conducted during the spring of 1985. The overall purposes of the field tests were to evaluate questionnaires and procedures to be used for the…

One means of Web use evaluation is through analysis of server-generated log files. Various log file analysis techniques and issues are presented that are related to the interpretation of log file data. Study findings indicate a number of problems; recommendations and areas needing further research are outlined. (AEF)
