ModisCfied Holt s Linear Trend Method

open access: yesHacettepe Journal of Mathematics and Statistics, 2017
Summary: Exponential smoothing models are simple, accurate and robust forecasting models and because of these they are widely applied in the literature. Holt's linear trend method is a valuable extension of exponential smoothing that helps deal with trending data. In this study we propose a modified version of Holt's linear trend method that eliminates
