Abstract:
With that work called “Time series and application to sales data”, it is tried to make a suitable guess model by analyzing the data of Danone Hayat A.Ş 2004-2010 sale data on the basis of liter. During the stagnation stage of the sequence correlogram and root analyses are performed. Same sequence is analyzed by the help of Eviews 5,1 computer software package. At the end of the survey, it is seen that natural logarithmic demijohn sale sequences is at its own level and in the first gap it is not constant and it is also seen that when the second gap is taken, the constant is obtained. The sequence of which the second gap is taken is shown on the basis of time-way graphs and correlogram. When the constant is provided, the guessed model is formed by taking the second gap. The suitability of the model is observed by the correlogram, Akaike information criteria (AIC) and Schwarz information criteria (SIC) merits.
