flation. The CPI excluding food and energy prices (core CPI) removes price changes of the same items from the CPI each month—namely, food and energy prices—because they are typically the most volatile
The median CPI and the trimmed-mean CPI use a different approach. These measures exclude the smallest and largest price changes during the month, so the items excluded from the CPI change from month to month. The median CPI excludes all price changes except for the one in the center of the distribution of price changes, where the price changes are ranked from lowest to highest (or most negative to most positive).
The 16 percent trimmed-mean CPI excludes price changes in specified upper and lower tails of the distribution. According to research from the Cleveland Fed, the median CPI provides a better signal of the underlying inflation trend than either the all-items CPI or the CPI excluding food and energy. The median CPI is even better at forecasting PCE inflation in the near and longer term than the core PCE price index.
