两种非标准的技术-拉西模型和非线性主成分分析-最初在其他领域提出并讨论了衡量欧洲公民对公用事业的意见。因此考虑了欧洲晴雨表的调查数据。强调了这两种方法及其补充使用的潜力；特别是，这些方法使调查表得以校准，不同服务的作用和服务的各个方面得以确立，消费者满意度得以评估和比较欧洲国家、不同年份和不同服务之间的情况。
Two non-standard techniques - the Rasch Model and Nonlinear Principal Components Analysis - originally proposed in other fields are presented and discussed to measure the opinion of European citizens about utilities. The Eurobarometer survey data are thus considered. The potential of both methods and their complementary use are highlighted; in particular the methods allow the questionnaire to be calibrated, the role of different services and aspects of service to be established, and the consumer satisfaction to be assessed and compared among European countries, different years and services.
