ABSTRACT
In statistical analysis, most of the time we are dealing with data which is timely ordered the same variable observed and measured at consecutive points of time. Sometimes we deal with information about different individuals at the same point of time or during the same time period. A particular commodity, say pesticide price, at a given point of time over different retail shops, constitutes a cross-sectional data. Time series modeling is a vibrant research area which grabbed attention of the researchers. The time series analysis also helps in isolating and measuring the various components of the time series. Time series also analysis helps in identifying the difference between the actual phenomenon and expectation of a realization. The oscillatory movement of a time series with recurrent upward and downward movement continuing more than a year is known as Cyclical Movement of the time series.
