01Attribution and view-through
Rule-based models (last click, first click, linear, time decay, position based) and a data-driven model run on the same touchpoints, with windows you choose. View-through credit is only added through one capped path: it can never exceed what was left as direct or unattributed, so it cannot inflate total revenue.
02When a marketing mix model is shown
The marketing mix model needs at least 56 days of daily data and is checked against days it was not trained on. If any validity check fails, Deltryx shows why and does not hand its numbers to reports or the assistant.
- Out-of-sample error and fit are reported with every run
- Implausible results flag the model: a negative baseline, nearly all revenue given to one channel, or an incremental return far beyond what spend can explain
- Channels whose spend moves together cannot be separated and are flagged as overlapping
- Confidence intervals come from repeated refits and are shown with every channel
03Incrementality tests
A geo or time holdout test reports a return only when spend actually moved during the test and the measured effect is outside the margin of error. Otherwise the result is reported as inconclusive, with no return figure.
04Margins and profit
Profit uses the margin measured from your order costs when they are available, and falls back to the margin you entered otherwise. The source of the margin is always shown next to the figure.
