Ecommerce

You can use Ecommerce Metrics in two different ways:

• With Polars
• As a Single Value Function (SVF)

Metric Forge extends the Polars expression library; making it possible to perform row-wise-calculations for various metrics. In addition to mass calculations, you can also perform single value calculations that return just one value.

import polars as pl
data = pl.read_csv('datasets/ecommerce_metrics.csv')
data.head()
