Abstract
This paper analyzes and predicts the Average Global Temperature time series data. Three different variants of ARIMA models: Basic ARIMA, Trend based ARIMA and Wavelet based ARIMA have been used to predict the average global temperature. Out of all the three linear models, it has been observed that Trend based ARIMA method outperforms basic ARIMA method and Wavelet based ARIMA method outperforms Trend based ARIMA method. MAPE (Mean Absolute Percentage Error), MaxAPE (Maximum Absolute Percentage Error) and MAE (Mean Absolute Error) have been used as a performance measures to compare between the models.
