Abstract

The method of successive intervals, a procedure for obtaining equal intervals from category data, is applied to social preference data for a health status index. Several innovations are employed, including an approximate analysis of variance test for determining whether the intervals are of equal width, a regression model for estimating the width of the end intervals in finite scales, and a transformation to equalize interval widths and estimate item locations on the new scale. A computer program has been developed to process large data sets with a larger number of categories than previous programs.

摘要

连续区间法是一种从类别数据中获取等距区间的程序,被应用于健康状况指数的社会偏好数据。采用了多项创新,包括用于确定区间宽度是否相等的近似方差分析检验、用于估计有限量表中末端区间宽度的回归模型,以及用于使区间宽度相等并在新量表上估计项目位置的变换。已开发出一个计算机程序来处理比以前程序具有更多类别的大数据集。
