Multi-Touch Attribution. Find out which channels contribute most to user conversion.

This package contains implementations the following Multi-Touch Attribution models:

• Shapley
• Markov
• So-called Simple Probabilistic Model by Shao and Li
• Bagged Logistic Regression by Shao and Li
• Additive Hazard (Survival)

In addition, some popular heuristic “models” are included, specifically

• First Touch
• Linear
• Last Touch
• Time Decay
• Position Based

The package comes with the same test data set as an R package called ChannelAttribution - there are 10,000 rows containing customer journeys across 12 channels: alpha, beta, delta, epsilon, eta, gamma, iota, kappa, lambda, mi, theta and zeta.

These are conversion aggregations by path. Suppose there’s a path (customer journey)

a > b > c

with total_conversions equal to 2 and total_null equal to 5. This means that we recorded 2 consumer journeys

a > b > c > (conversion)

and 5 customer journeys

a > b > c > (null)

There’s an option to generate timestamp data if you want to use the Additive Hazard model (the only model that explicitly incorporates exposure times).
