meridian.analysis.visualizer.ReachAndFrequency

Generates reach and frequency plots for the Meridian model.

meridian.analysis.visualizer.ReachAndFrequency(
    meridian: model.Meridian,
    selected_times: (Sequence[str] | None) = None,
    use_kpi: bool = False
)

Plots the ROI by frequency for reach and frequency (RF) channels.

Args
meridian	Media mix model with the raw data from the model fitting.
selected_times	Optional list containing a subset of times to include. By default, all time periods are included.
use_kpi	If True, KPI is used instead of revenue.

Attributes
optimal_frequency_data	Dataset holding the calculated optimal reach and frequency metrics. The dataset contains the following: Coordinates: frequency, rf_channel, metric (mean, ci_hi, ci_lo) Data variables: roi, optimal_frequency

plot_optimal_frequency(
    selected_channels: (list[str] | None) = None
)

Plots the optimal frequency curves for selected channels.

Args
selected_channels	Optional list of RF channels to plot.

Returns
A faceted Altair plot showing a curve of the optimal frequency for the RF channels.

update_optimal_reach_and_frequency_selected_times(
    selected_times: (Sequence[str] | None) = None
)

Updates the selected times for optimal reach and frequency data.

Args
selected_times	Optional list containing a subset of times to include. By default, all time periods are included.
