The researchers analyzed the seasonality of Consumer Price Index Numbers for Industrial Workers (CPI-IW) using a model called X-12 ARIMA. They found that the CPI-IW shows identifiable seasonality but no significant moving seasonality. This information can help understand trends in the economy and study monthly growth rates.
