Multivariate

This module provides a simple interface for setting up multivariate or A/B style studies that can be performed on a live sites to test the effectiveness of various interfaces.

Update - Dec 9th 2011

Initial dev version of 7.x branch is in git. I have not yet tested it extensively--will be doing this over the next few days.

I'd like to spend a lot of time with this module and make it a really strong competitor to some of the 3rd party based multivariate studies out there. I believe that the multivariate version of this module, which can hook into Drupal to change things nearly anywhere on the site is far more powerful than anything a 3rd party offering can do.

Things to add (open issues if there are things you'd like)

• Additional documentation on how to create multivariate mutations
• Context awareness to allow studies to change contexts on the site (this will allow for changing anything context can change, such as blocks or themes)
• Cookie time per study

Multivariate
Any portion of Drupal may be modified using the hooks and mechanisms already in place. The modifications may be based on multivariate mutations. Once a mutation set is requested the same set will be used for the entire user session. The mutation information may be used to make any modification to forms and such. An example multivariate mutation is provided and demonstrates how simple it is.

A/B
Setting up an A/B style test is very simple and only requires the original URL, and any variation URLs. When a user visits the original URL a mutation will be selected that will either redirect them to one of the variations or leave them on the original URL. The same mutation will be used for the entire user session.

Success
Success is counted when a user visits the success URL specified in the study details. For example, this could be a page that the user is redirected to after they buy a product. If a more complex success condition is required the module provides a hook for defining complex conditions.
