^[1] Indexes calculated using 100% non-sampled price data from one or more alternative data sources will not have variance due to sampling and have standard errors coded as not applicable (n.a.). Indexes calculated using a mix of directly collected price data and price data from one or more alternative data sources will have lower standard error values as the proportion of non-sampled trade value increases. ^[2] Index was not published the previous year. Estimates using prior year index values are excluded.
