Abstract
Time series analysis of Nigerian Consumer Price Index (NCPI) Data is done. It is observed that it is seasonal. A multiplicative seasonal autoregressive integrated moving average (ARIMA) model , (0, 1, 1)x(0, 1, 1)12, is fitted to the series. A visual inspection of the actual and the fitted time plots reveals a close agreement between the two.
