Andreas Graefe (http://www.andreas-graefe.org/index.php) has helped Scott Armstrong and Kesten Green to update ForPrin.com's answers to Frequently Asked Questions (or FAQs) about forecasting. There are many changes throughout the FAQs, but one important change is the addition of material on the I… ndex Method in the answer to a question on how to make best use of expert knowledge about causality when making forecasts. The answer to that question is available here (http://www.forecastingprinciples.com/index.php?option=com_content task=view id=3 Itemid=3#types%207). The FAQs can be found on the left menu bar of this page, or here (http://www.forecastingprinciples.com/index.php?option=com_content task=view id=3 Itemid=3). As with all content on the site, we welcome suggestions and corrections. Please send your feedback to Kesten (mailto:kesten@me.com?subject=ForPrin.com%20site%20feedback.).
