Important

We have migrated all our documentation to the more complete and modern class multidimensional.MMM. See the migration guide: https://www.pymc-marketing.io/en/latest/notebooks/mmm/mmm_migration_guide.html
We will remove the old mmm.MMM class in 0.20.0. Please migrate your code! Most changes are internal optimizations. The APIs are very similar!
