Goal

This project will be an attempt to create a tool for easy use and access of probability tables. It will likely be in the form of a Javascript webpage with the ability to import/export files. Hopefully this will be a useful tool for those online prophets who want to be precise, public, and bold in their predictions.

Order of tasks is (very) roughly as follows:

• Creation of variables that can referenced in table creation
• Allow creation of multiple boolean variable tables, such as:

  • X	P(X)
    +X	.4
    -X	.6

• Allow creation of conditional boolean variable tables, such as:

  • Y	X	P(X|Y)
    +Y	+X	.4
    +Y	-X	.6
    -Y	+X	.3
    -Y	-X	.7

• Move from marginal and conditional distribution tables to joint distribution tables (formatting TBD):

  • X	Y	P(X,Y)
    +X	+Y	.xxx
    +X	-Y	.xxx
    -X	+Y	.xxx
    -X	-Y	.xxx

• Go from a joint distribution table to a set of marginal and conditional probability tables
• Variables with more than 2 states
• Perform queries on the data, so rather than finding a table P(X,Y), P(X), or P(X|Y), simply enter it as a query and get the table/number.
• Import and export a set of tables
• An embeddable export option for blogs
• Save a document to the cloud that can be linked to for public reference.
