| There are a number of methods available to study time-series data. In this study, an attempt has been made to examine the Linear Trend
Regression, Holt and Winter Models and compare their forecast quality by
using times series data of the production of Indian Automobiles during
1996-97 to 2007-08. Forecasts using these methods are presented and
Comparison Statistics and Statistics of Errors for the methods were
examined. It is found that Winter’s Model Forecasting produced better
results than the rest of the methods, as seen on the Mean Absolute
Percentage Error (MAPE). |
