BetaGeoFitter: RuntimeWarning: overflow encountered in double_scalars

See original GitHub issue

Running this

from lifetimes.plotting import plot_frequency_recency_matrix

_, ax = plt.subplots(1, 1, figsize=(10, 8))
plot_frequency_recency_matrix(bgf);

on a bgf with parameters lifetimes.BetaGeoFitter: fitted with 2556392 subjects, a: 0.40, alpha: 50.16, b: 0.81, r: 0.10

results in

beta_geo_fitter.py:205: RuntimeWarning: overflow encountered in double_scalars
  denominator = 1 + (x > 0) * (a / (b + x - 1)) * ((alpha + T) / (alpha + recency)) ** (r + x)

The plot still shows up though.

Hi @zerualem , did you find a solution? Or was resampling by week the best solution?

For now, re-sampling is the only option for me. Read here also Overcoming the BG/NBD Model’s #NUM! Error Problem
