An Overview of the BayES Desktop

This video tutorial provides a quick tour of the BayES desktop. It also defines some of the terminology used in the tutorials that follow and in the documentation.

Importing, Summarizing and Plotting Data

This video tutorial demonstrates how data can be imported into BayES, viewed in the data-viewer window, summarized and plotted using different graph types. It also shows how new variables can be added to a dataset and how data can be exported to .csv files for processing by other programs.

Running Models from the GUI

This video tutorial demonstrates how a linear model can be run in BayES using the Graphical User Interface (GUI) and how the results can be visualized. Parts of the model-specification dialogues that are common to all models (for example, specification of the Gibbs-sampler parameters and prior parameters) are also described. The tutorial concludes by showing how workspaces can be saved before exiting BayES and reloaded from memory.

Working with Code: The BayES Script Editor

This video tutorial provides a tour of BayES' script editor and shows how simple commands, like defining matrices and printing on the BayES console, importing data and running simple models, can be submitted for execution.

Working with BayES from the Command Shell

This video tutorial demonstrates how BayES can be run from the system's command shell and asked to execute the statements contained in a file, without firing-up the GUI. It also shows how any output intended for the BayES console can be redirected to a file.

Writing and Executing BayES Functions

This video tutorial demonstrates how user-defined functions work in BayES. A simple function is first defined in a script file and the file is saved. Another script file is then prepared, which executes the function and prints its return values on the console.
