Which attribution models does the multi attribution feature support?

Multi Channel Conversion Attribution supports the following attribution models:

• Last Interaction: The full credit of a conversion goes to the last interaction.
• Last Non Direct Interaction: The full credit of a conversion goes to the last interaction that was not a direct entry.
• First Interaction: The full credit of a conversion goes to the first interaction.
• Linear: The credit of a conversion is shared equally across all interactions. If there are for example 5 visits, each channel / referrer gets 20% of the credit.
• Position Based: The first and the last interaction get each 40% of the credit. The remaining 20% of the credit are shared equally across all remaining interactions.
• Time Decay: The credit of a conversion is shared across all interactions where more recent interactions become more credit compared to interactions that happened a longer time ago.
