Sylvia Leaver and William Larson (2001) "Estimating Variances for a Scanner-Based Consumer Price Index."
In this paper we present estimates of the sampling variance of price change for an experimental scanner-based Consumer Price Index for cereal for the New York Consolidated Metropolitan Area. Variances are presented for 1-, 6- and 12-month price change lags, using a stratified jackknife methodology. Estimates are contrasted with variance estimates for the published price index for cereal for the same area. Sources of price change variability are identified and discussed.
