  • Delphi - Multi-round surveys of experts where anonymous feedback on the groups' responses and on reasoning is provided to the experts after each round.
  • Delphi software user guide - in the form of PowerPoint slides with voiceover intrstructions originally developed to instruct participants in an experiment.
  • For evidence on the use of Delphi under various conditions, see "Comparing face-to-face meetings, nominal groups, Delphi and prediction markets on an estimation task".
  • Econometric Models:
    • Econometrics Journal provides links to around 150 programs, some of which are free, and links to relatedt sites which evaluate software.
    • The FairModel Site provides econometric models that can be used to make several analyses of policies.
  • Forecast Package for R provides tools to forecast using time-series data in Language R for Windows. It contains:
    • 24 exponential methods (smoothing in the state space modeling framework) from Hyndman, Koehler, Snyder and Grose, International Journal of Forecasting, 2002, 18, 439-454).
    • automatic selection of model ARIMA
    • graphical methods to show time series
    • sets of data from Makridakis, Wheelwright and Hyndman (1998), Forecasting: methods and applications, Wiley & Sons: New York. See review.
  • Regressit is a free Excel add-in for regression and multivariate analysis.
    • Developed by Bob Nau (Duke) and John Butler (U. Texas)
    • Appropriate for professional practice as complement to or substitute for other regression software
    • Multivariate descriptive data analysis and linear regression
    • Features support transformations and good modeling practices
    • Detailed statistics, and presentation quality plots, tables, and charts.
  • ESCI ("ESS-key", Exploratory Software for Confidence Intervals)
      • ESCI is a free download from and accompanies the book Understanding The New Statistics (Routledge, 2012), by Geoff Cumming.
      • ESCI runs under Microsoft Excel, on Windows or Mac. ESCI provides interactive simulations designed to help understanding of sampling, confidence intervals, estimation, replication, and meta-analysis. It also calculates and graphs confidence intervals for a useful range of measures and designs.
    • PEERForecaster Add-in for Excel: A univariate time series forecasting package.
      • An implementation of the state-space models from Hyndman, Koehler, Snyder and Grose, International Journal of Forecasting, 2002, 18, 439-454.
      • Include all the well-known techniques from simple smoothing, Holt trending, Holt-Winters seasonal models, and damped trend exponential smoothing models to the Box Jenkins ARIMA models.
      • Would be useful to practitioners for benchmarking and validating comparable models found in expensive demand planning systems.
      • The algorithms and model interpretations are documented in Levenbach and Cleary (2005) Forecasting: Practice and Process for Demand Management, Cengage Publishers.
    • Free 30-day trial of Autobox. There are no limitations other than the 30 days. Vista and Windows 7.0 users need to save the install and then right click and choose "run as admin" to install. To run, the same steps apply.
    • Neural nets - neural software from the Portal on Forecasting with Artificial Neural Networks
    • Open Forecast regression and smoothing programs for time series
    • Previsao: Regression package based on EXCEL in VisualBasic (in Portuguese)
    • Seasonal Adjustment Program
      • The X-12-ARIMA software for seasonal adjustment, developed by the U.S. Census Bureau, replaces the program X-11. Select and download omega.exe to use in a PC with Windows. Some users prefer to use X-11, since there are no verified benefits for using X-12 for forecasting, compared with X-11.
    • Damped Seasonal Adjustment
      • There are two zip files that can be downloaded. To damp seasonals of ratio-to-moving average (classical) decomposition, download the file To damp seasonals from X12, download the file instructions are in the zip files. Questions about this freeware or seasonal damping may be directed to Dan Williams or Don Miller. Because this software is provided free of cost, the authors request that you provide feedback concerning your experience.
