Comparison of Multiple Linear Regression and Holt-Winter Exponential Smoothing in the Gold Jewelry Pricing Prediction

One important factor in someone's decision to purchase gold jewelry is the price factor. However, of varies from store store. Therefore, a forecasting system needed assist customers determining right time buy jewelry. This study aims develop prediction by comparing two methods: multiple linear regression and Holt-Winter exponential smoothing. These methods were chosen because researcher wants compare which method more accurate predicting The second reason that both smoothing share similarities using three variables. variables include period (X1), profit (X2), (Y), while level, trend, season.
