چکیده
Fall 2008 Issue 11 FORESIGHT Stephan Kolassa is Vice President of Corporate Research at SAF AG in Switzerland. He has worked extensively with some of Europe’s largest retail chains in producing automatic forecasts for large batches of products. Stephan and his colleague Wolfgang Schütz coauthored “Advantages of the MAD/MEAN Ratio Over the MAPE” in Foresight’s Spring 2007 issue. INTRODUCTION Sales forecasters are frequently asked what a “good” forecast is; that is, what accuracy should be expected from the forecasting method or process?

The Qualitative Descriptive Approach in International Comparative Studies: Using Online Qualitative Surveys
International comparative studies constitute a highly valuable contribution to public policy research. Analysing different policy designs offers not only a mean of knowing the phenomenon itself but also gives us insightful clues on how to improve existing practices. Although much of the work carried out in this realm relies on quantitative appraisal of the data contained in international databa...
متن کاملThe Variance-covariance Method using IOWGA Operator for Tourism Forecast Combination
Three combination methods commonly used in tourism forecasting are the simple average method, the variance-covariance method and the discounted MSFE method. These methods assign the different weights that can not change at each time point to each individual forecasting model. In this study, we introduce the IOWGA operator combination method which can overcome the defect of previous three combin...
متن کاملQuantifying IT forecast quality
In this paper, we showed how to quantify the quality of IT forecasts based on Boehm’s cone of uncertainty and DeMarco’s Estimating Quality Factor. With these, we support decision making by providing critical information on IT forecasting quality to IT governors. We illustrated that plotting forecast to actual ratios against a predefined referential conical shape reveals potential biases, for in...

متن کاملTests of Equal Forecast Accuracy and Encompassing for Nested Models
We examine the asymptotic and finite-sample properties of tests for equal forecast accuracy and encompassing applied to 1-step ahead forecasts from nested parametric models. We first derive the asymptotic distributions of two standard tests and one new test of encompassing. Tables of asymptotically valid critical values are provided. Monte Carlo methods are then used to evaluate the size and po...
