cofilter

Description

Use this command to find how many times field1 and field2 values occurred together.

This command implements one step in a collaborative filtering analysis for making recommendations. Given a user field (field1) and an item field (field2), it finds how common each pair of items is. That is, it computes sum(A has X and A has Y) where X and Y are distinct items and A is each distinct user.

Syntax

cofilter <field1> <field2>

Required arguments

field1
Syntax: <field>
Description: The name of field.
field2
Syntax: <field>
Description: The name of a field.


Examples

Example 1:

Find the cofilter for user and item. The user field must be specified first and followed by the item field. The output is event for each pair of items with: the first item and its popularity, the second item and its popularity, and the popularity of that pair of items.

... | cofilter user item

Comments

Based on the docs for both commands, I believe that `contingency` should be in the `see also` section. I am not sure because I cannot get `cofilter` to work in some test. Perhaps the `cofilter` command doesn't work or is deprecated?
