Using various sources of expenditure data, Statistics Canada, in partnership with the Bank of Canada, has estimated monthly adjusted consumer expenditure weights that reflect shifts in consumption patterns as the COVID-19 pandemic evolves. The Adjusted price index has been updated to incorporate the 2020 basket weights and is now based on a Similarity-linked Fisher price index formula. The expenditure data cover all goods and services in the Consumer Price Index (CPI), and provide snapshot estimates of expenditure weights for June, July, August and September 2021. These estimates can provide insight into the impact of COVID-19 on the headline CPI.
Release date: 2021-11-10 - Articles and reports: 11-522-X202100100012Description: The modernization of price statistics by National Statistical Offices (NSO) such as Statistics Canada focuses on the adoption of alternative data sources that include the near-universe of all products sold in the country, a scale that requires machine learning classification of the data. The process of evaluating classifiers to select appropriate ones for production, as well as monitoring classifiers once in production, needs to be based on robust metrics to measure misclassification. As commonly utilized metrics, such as the Fß-score may not take into account key aspects applicable to prices statistics in all cases, such as unequal importance of categories, a careful consideration of the metric space is necessary to select appropriate methods to evaluate classifiers. This working paper provides insight on the metric space applicable to price statistics and proposes an operational framework to evaluate and monitor classifiers, focusing specifically on the needs of the Canadian Consumer Prices Index and demonstrating discussed metrics using a publicly available dataset.
