PPT-Ratio Transformation for Stationary Time Series with

Special Application in Consumer Price Index in Qatar By Adil Yousif Hind Alrkeb Doha Alhashmi Department of Mathematics and Statistics Qatar University Doha Qatar Abstract This article was intended to perform a comprehensive time series analysis for Consumer Price Index CPI in Qatar The data was obtained from the Statistics Authority in Qatar For the period between 20022009 a quarterly data was analyzed using several time series techniques such as Exponential Trend method Holts Trend method and ARIMA These methods were used to examine trends and built a forecast model Ratio transformation technique was used to obtain a stationary time series and found to be efficient with small size of data.
