Release Version 6.4 includes many bug fixes and powerful new functionality, as detailed below.
These include:
•Optimization improvements
oAll optimization settings, including MCMC, stochastic optimization and extended payoff types are now available directly from the user interface. See the sections on Payoff Definitions and Optimization for more details.
oPayoff reports have been improved
oA new payoff type permits elements that contribute to Kalman filter updates but not to the optimization payoff
oPayoffs now skip points with NA values of model variables
oMinor bug fix to prevent randomization of MCMC internal processes
oFaster payoff computation
oKalman filter stability has been improved, particularly for models with many measurements and few states
•Sensitivity simulation improvements
oThe VECTOR distribution has new options for testing only endpoints
oImproved distribution parameter validation
oEnhanced data export - see next item.
•Data import/export - new functionality makes it easier to work with enterprise data sources, statistics, visualization and business intelligence packages
oVensim can now import and export two new data types, relational and tidy. See: VDF2DLIST, VDF2TIDY, DLIST2VDF, TIDY2VDF
oSensitivity simulation export has been greatly enhanced, and also includes tidy and relational formats - see SENS2FILE
•The Runs Compare tool can now be used with non-simulation sources (i.e. .vdf files from data)
•Many bug fixes on the Mac.
