Channel Uncertainty Driversn report

Recast digs into your variance to learn about why there may be a high variance in some of your channel estimates. This is visualized in the variance decomposition Channel Uncertainty Drivers report. A high variance may be due to lack of spend, or correlation with another channel, spikes or the intercept.

Technical summary

Setup: for the selected time-period, we sum the daily impact estimates for each channel for each draw to get a 500 x n_channels matrix of (say) total monthly impact.
