Examples

Gains Loss Analysis

Here is an excerpt from the gain loss analysis example notebook

from pyretailscience.analysis.gain_loss import GainLoss

gl = GainLoss(
    df,
    # Flag the rows of period 1
    p1_index=time_period_1,
    # Flag the rows of period 2
    p2_index=time_period_2,
    # Flag which rows are part of the focus group.
    # Namely, which rows are Calvin Klein sales
    focus_group_index=df["brand_name"] == "Calvin Klein",
    focus_group_name="Calvin Klein",
    # Flag which rows are part of the comparison group.
    # Namely, which rows are Diesel sales
    comparison_group_index=df["brand_name"] == "Diesel",
    comparison_group_name="Diesel",
    # Finally we specifiy that we want to calculate
    # the gain/loss in total revenue
    value_col="total_price",
)
# Ok now let's plot the result
gl.plot(
    x_label="Revenue Change",
    source_text="Transactions 2023-01-01 to 2023-12-31",
    move_legend_outside=True,
)
plt.show()

Cross Shop Analysis

Here is an excerpt from the cross shop analysis example notebook

from pyretailscience.analysis import cross_shop

cs = cross_shop.CrossShop(
    df,
    group_1_col="category_name",
    group_1_val="Jeans",
    group_2_col="category_name",
    group_2_val="Shoes",
    group_3_col="category_name",
    group_3_val="Dresses",
    labels=["Jeans", "Shoes", "Dresses"],
)
cs.plot(
    title="Jeans are a popular cross-shopping category with dresses",
    source_text="Source: Transactions 2023-01-01 to 2023-12-31",
    figsize=(6, 6),
)
plt.show()
# Let's see which customers were in which groups
display(cs.cross_shop_df.head())
# And the totals for all groups
display(cs.cross_shop_table_df)

Customer Retention Analysis

Here is an excerpt from the customer retention analysis example notebook

ax = dbp.plot(
    figsize=(10, 5),
    bins=20,
    cumulative=True,
    draw_percentile_line=True,
    percentile_line=0.8,
    source_text="Source: Transactions in 2023",
    title="When Do Customers Make Their Next Purchase?",
)

# Let's dress up the chart a bit of text and get rid of the legend
churn_period = dbp.purchases_percentile(0.8)
ax.annotate(
    f"80% of customers made\nanother purchase within\n{round(churn_period)} days",
    xy=(churn_period, 0.81),
    xytext=(dbp.purchase_dist_s.min(), 0.8),
    fontsize=15,
    ha="left",
    va="center",
    arrowprops=dict(facecolor="black", arrowstyle="-|>", connectionstyle="arc3,rad=-0.25", mutation_scale=25),
)
ax.legend().set_visible(False)
plt.show()
