What is the purpose of `calculate_main_effects`?

This tool answers which individual elements or variants are driving the most significant change in conversions by calculating the average performance impact of switching a factor from its baseline to its variant level.

How can I detect if two elements work better together?

Use the `analyze_interaction_effects` tool. It compares the observed performance of two-factor combinations against the expected performance if they acted independently, identifying significant dependencies.

How do I find the best configuration for my test?

The `identify_winning_combination` tool identifies the specific setup with the highest conversion rate and verifies if it is statistically significantly better than the baseline using error variance analysis.

More Details Connect to Claude

The Multivariate Test Analyzer is a statistical engine designed for simplified 2k Factorial Design of Experiments (DOE). It allows AI agents to analyze complex multivariate tests by evaluating how different elements (factors) and their variants impact conversion rates. By using tools like calculate_main_effects, analyze_interaction_effects, and identify_winning_combination, you can isolate the direct impact of individual elements, detect dependencies between pairs of factors, and pinpoint the statistically optimal configuration for your experiments.
