How to create custom impression detection function for Randomized Tests
2 Comments | Posted by admin in A/B Split Tests, UTI, Uncategorized
Randomized Tests version 1.3 introduces new feature – custom impression functions. It allows You to decide who and under what conditions participates in A/B split test. In this post I would like to show You how to create custom impression detection function and how to use it to speed up experiments.
The need for custom impression [...]
It’s mainly bug fix release. Update is STRONGLY recommended.
Changelog:
Changed file name of includes/auto_loaders/config.utis.php.php to includes/auto_loaders/config.utis.php
uti_install.sql missed some inserts
Fix to: [DELETE FROM uti_attributes WHERE uti_row_id = ? AND name IN () ]
UTI tables now use DB_PREFIX
You can download it from: Current version of UTI.
It seems that I’ve forgotten to add installation commands to the sql installation file and there are no options under ‘UTI Variables’ in Configuration Menu. To Go to Admin->Tools->Install SQL patches and execute following commands:
SELECT (@group_id:=configuration_group_id) FROM configuration_group WHERE configuration_group_title LIKE ‘UTI Variables’;
INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order) VALUES(‘[Recent Products] Max recent [...]
Randomized tests version 1.3 is here (download). This release brings quite few new features that should be very helpful. I added 95% trust intervals for each statistic. There’s also probability that given experiment will beat control group. You can now also decide when impression occurs. Read below for more.
Installation
Refer to INSTALL.txt in .zip file.
If You [...]

Randomized Tests V1.2 for Zen Cart Released
0 Comments | Posted by admin in A/B Split Tests, Utils
New version of Randomized Tests for Zen Cart is available. New version introduces few bug fixes and one very important feature – orders filters and customer filter. Order/Customer filters can be used to dynamically remove (not permanently) from statistics certain customers/orders and recalculate statistics without them. Why is it important?
Let’s assume that You have store [...]
This module allows You to perform experiments on Your website. You can test for example how Your new ‘Add to Cart’ button performs compared to old one.
I don’t have much time to write long post, so I’ll cut it to most important things. You can download the module here. This module requires UTI to work [...]
UTI is tiny module that tracks visitors to Zen Cart site even if they aren’t logged in or even never created any account. It allows developers to keep in UTI memory small amounts of information about each visitor. For example, UTI can be used to store list of recently viewed products by any particular user. [...]
I’ve created User Tracking Interface (UTI) module for Zen Cart v1.3.8 which recognizes visitors (even if they are not logged in or don’t have account) and stores simple bits of information about them in database. You can use UTI to store such information as favorite currency of each visitor, recently viewed products by particular visitor [...]
In my work I test various changes in Zen Cart code and measure performance. To do this, I need quite large database of products, categories and manufacturers. I like to test changes with 1k, 10k, 100k and one million products and 1k, 10k manufacturers / categories to see how zen cart scales. I need to [...]
