Research indices using web scraped price data - Appendix tables

This workbook presents experimental price indices that are constructed from ONS web scraped data from three grocery retailers since May 2014. These are early analysis using experimental techniques to help us develop our statistical methodology and are not comparable with headline estimates of inflation. We would strongly caution against their use in economic modelling and analysis.本工作簿呈现了自2014年5月起，基于英国国家统计局(Office for National Statistics)从三家食品杂货零售商处获取的网络爬取数据构建的试验性价格指数。本项分析为采用试验性方法开展的早期研究，用于助力我们完善统计方法体系，且该指数不可与官方公布的通胀总体估算值进行对比。我们强烈提醒请勿将其用于经济建模与分析工作。
