DecompositionPlots

class pymc_marketing.mmm.plotting.decomposition.DecompositionPlots(data)

Decomposition plots for fitted MMM models.

Provides three methods to visualize how the model decomposes the target:

• contributions_over_time — Time-series of each contribution type with HDI.

• waterfall — Horizontal waterfall chart of mean contributions.

• channel_share_hdi — Forest plot of each channel’s share of total response.

Parameters:

dataMMMIDataWrapper

Validated wrapper around the fitted model’s InferenceData.

Methods

DecompositionPlots.__init__(data)
DecompositionPlots.channel_share_hdi([...])	Forest plot of each channel's share of total channel contribution.
DecompositionPlots.contributions_over_time([...])	Plot time-series contributions for selected contribution types with HDI bands.
DecompositionPlots.waterfall([...])	Horizontal waterfall chart showing mean contribution per component.
