BayesiaLab 8

New Release: BayesiaLab 8

Since 2001, BayesiaLab has been the undisputed reference standard for Bayesian network software. Version 8 raises the bar even higher by further expanding the range of research and analytics applications of the Bayesian Network formalism. With BayesiaLab 8, the powerful properties of the Bayesian Network paradigm can be utilized even better for exploring complex, high-dimensional problem domains.

New & Updated Features & Functions

Here is a small selection of new or updated features released in BayesiaLab 8:

  • The Start-Up Page gives you quick access to BayesiaLab's main functions and recent networks.
  • You can choose the Appearance of each node from five predefined graphical elements: Disc, Badge, Monitor, Gauge, and Bar.
  • When copying nodes, arcs, and notes, you can also Paste the Format of these objects.
  • The Data Import Wizard suggests the number of bins for the discretization of your continuous variables according to the number of observations in your data set.
  • R2-GenOpt*, an extended version of R2-GenOpt, utilizes a specific MDL score for choosing a suitable number of bins.
  • Parameter Updating takes into account the observations set in the monitors for updating the quantitative part of the Bayesian network.
  • In addition to the Multi-Quadrant Analysis, you can analyze segmented datasets with the Impact on Target and Profile tools. 
  • You can use Search to find and run Actions.
  • You can directly associate Long Names with nodes without having to use the Node Comment field.
  • The brand-new WebSimulator Editor allows you to define and test all settings of your simulator within BayesiaLab before publishing it.
  • Users of BayesiaLab Floating Token Licenses can define an Inactivity Timeout for Automatic Disconnect with the Bayesia License Server.

Additionally, a completely new set of icons gives BayesiaLab 8 a fresh and sharp look across all devices, screen sizes, and resolutions.
