Transforming Qualitative Survey Data: Performance Comparisons for the UK*
评估了将调查中的定性数据转换为定量指数的不同方法，聚焦英国制造业雇主调查，发现平衡统计法对投资、产出和出口三个变量转换效果良好。
Abstract This paper assesses different ways of converting qualitative data obtained in surveys into quantitative indices for a number of economic variables. The research reported here focuses on the main UK employers’ business survey for manufacturing – the CBI industrial trends survey. Six response variables are investigated – plant and machinery investment, output, employment, exports, price and cost. We find that the balance statistic is a satisfactory method of transforming three of the variables: investment, output and exports.
