Seasonal Characteristics of Indian Time Series


  • R. Krishnan

    (Indira Gandhi Institute of Development Research, Mumbai, India)


In this paper, seasonal behaviour of many Indian time series is analysed to check for stochastic seasonality. The results obtained using popular test procedures give contradictory results, though the general conclusion is that there is no evidence of seasonality being stochastic. Hence, the traditional way of using multiplicative filter or Census X-11 to remove seasonality is really not required in many cases. The existence of a unit root at the zero frequency, however, is confirmed for all but the stock returns series, along with fact that the first difference filter for should be augmented with other filters to make it stationary. Seasonal dummies account for a sizable portion of the fluctuations in the differenced series.
