Quick Installation Guide for Marketing Mix Modeling (MMM) & CLV

To dive into MMM and CLV analytics, set up a specialized Python environment, marketing_env, via conda-forge:

conda create -c conda-forge -n marketing_env pymc-marketing
conda activate marketing_env

For a comprehensive installation guide, refer to the official PyMC installation documentation.

Docker

We provide a Dockerfile to build a Docker image for PyMC-Marketing so that is accessible from a Jupyter Notebook. See here for more details.

In-depth Bayesian Marketing Mix Modeling (MMM) in PyMC

Leverage our Bayesian MMM API to tailor your marketing strategies effectively. Leveraging on top of the research article Jin, Yuxue, et al. “Bayesian methods for media mix modeling with carryover and shape effects.” (2017), and extending it by integrating the expertise from core PyMC developers, our API provides:

Feature	Description
Custom Priors and Likelihoods	Tailor your model to your specific business needs by including domain knowledge via prior distributions.
Adstock Transformation	Optimize the carry-over effects in your marketing channels.
Saturation Effects	Understand the diminishing returns in media investments.
Customize adstock and saturation functions	You can select from a variety of adstock and saturation functions. You can even implement your own custom functions. See documentation guide.
Time-varying Intercept	Capture time-varying baseline contributions in your model (using modern and efficient Gaussian processes approximation methods). See guide notebook.
Time-varying Media Contribution	Capture time-varying media efficiency in your model (using modern and efficient Gaussian processes approximation methods). See the guide notebook.
Visualization and Model Diagnostics	Get a comprehensive view of your model's performance and insights.
Choose among many inference algorithms	We provide the option to choose between various NUTS samplers (e.g. BlackJax, NumPyro and Nutpie). See the example notebook for more details.
GPU Support	PyMC's multiple backends allow for GPU acceleration.
Out-of-sample Predictions	Forecast future marketing performance with credible intervals. Use this for simulations and scenario planning.
Budget Optimization	Allocate your marketing spend efficiently across various channels for maximum ROI. See the budget optimization example notebook
Experiment Calibration	Fine-tune your model based on empirical experiments for a more unified view of marketing. See the lift test integration explanation for more details. Here you can find a Case Study: Unobserved Confounders, ROAS and Lift Tests.

MMM Quickstart

import pandas as pd

from pymc_marketing.mmm import (
    GeometricAdstock,
    LogisticSaturation,
    MMM,
)

data_url = "https://raw.githubusercontent.com/pymc-labs/pymc-marketing/main/data/mmm_example.csv"
data = pd.read_csv(data_url, parse_dates=["date_week"])

mmm = MMM(
    adstock=GeometricAdstock(l_max=8),
    saturation=LogisticSaturation(),
    date_column="date_week",
    channel_columns=["x1", "x2"],
    control_columns=[
        "event_1",
        "event_2",
        "t",
    ],
    yearly_seasonality=2,
)

Initiate fitting and get a visualization of some of the outputs with:

X = data.drop("y",axis=1)
y = data["y"]
mmm.fit(X,y)
mmm.plot_components_contributions();

Once the model is fitted, we can further optimize our budget allocation as we are including diminishing returns and carry-over effects in our model.

Explore a hands-on simulated example for more insights into MMM with PyMC-Marketing.

Unlock Customer Lifetime Value (CLV) with PyMC

Understand and optimize your customer's value with our CLV models. Our API supports various types of CLV models, catering to both contractual and non-contractual settings, as well as continuous and discrete transaction modes.

Explore our detailed CLV examples using data from the lifetimes package:

Examples

	Non-contractual	Contractual
Continuous	online purchases	ad conversion time
Discrete	concerts & sports events	recurring subscriptions

CLV Quickstart

import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
from pymc_marketing import clv

data_url = "https://raw.githubusercontent.com/pymc-labs/pymc-marketing/main/data/clv_quickstart.csv"
data = pd.read_csv(data_url)
data["customer_id"] = data.index

beta_geo_model = clv.BetaGeoModel(data=data)

beta_geo_model.fit()

Once fitted, we can use the model to predict the number of future purchases for known customers, the probability that they are still alive, and get various visualizations plotted.

See the Examples section for more on this.
