The Data Book gives you a direct view into the BigQuery table that was used to train the MMM model. It’s useful for verifying that the data is complete and correctly formatted before a model run, and for understanding what the model actually learned from.Documentation Index

What it shows
When you open Insights → MMM → Data Book, Interact queries your configured BigQuery table and displays:- Time range — first and last date in the dataset, and the number of observation periods
- All columns — one column per metric or channel variable, with values per date
- Excluded columns — columns listed in the “Excluded Columns” setting are hidden from the view
Switching between input and final table
If you configured a Final Table in the MMM settings, a toggle appears at the top of the Data Book to switch between the raw input table and the adjusted/final version. Use the final table view to verify post-processing steps (e.g. spend normalization or outlier corrections) before running the model.Multi-market configs
If you have more than one Data Book configured (e.g. NL and DE), a label dropdown appears at the top of the page. Select a market to switch which dataset is shown.Validating your data
Before running the Meridian pipeline, use the Data Book to check:Date continuity
Confirm there are no unexpected gaps in the date sequence. Meridian expects a complete, contiguous time series.
Spend columns present
Every channel that will be modelled should appear as a column. Channels missing from the table cannot be included in the model.
