💡 Quick Examples

import bizlens as bl
import pandas as pd

# Load a built-in teaching dataset (returns pandas DataFrame)
df = bl.load_dataset('titanic')   # or 'tips', 'iris', 'penguins', 'diamonds', 'mpg'

# Frequency distribution
bl.tables.frequency_table(df['sex'])

# Summary statistics
bl.tables.summary_statistics(df[['age', 'fare']])

# Contingency table with chi-square test
table, stats = bl.tables.contingency_table(df, 'sex', 'survived')
print(f"Chi² = {stats['chi2']:.3f}, p = {stats['p_value']:.4f}, Cramér's V = {stats['cramers_v']:.3f}")

# Data quality profile
bl.quality.data_profile(df)

# Confidence interval
import numpy as np
bl.inference.confidence_interval(df['age'].dropna(), confidence=0.95)

# Two-sample t-test
bl.inference.two_sample_ttest(df[df['sex']=='male']['fare'], df[df['sex']=='female']['fare'])

Process Mining

# Load a built-in event log (returns pandas DataFrame)
event_log = bl.generate_hr_onboarding_event_log()

bl.process_mining.case_metrics(event_log)
bl.process_mining.bottleneck_analysis(event_log)
bl.process_mining.variant_discovery(event_log)
bl.process_mining.resource_analysis(event_log, resource_col='resource')

Polars Users

# BizLens also accepts polars DataFrames
import polars as pl
df_pl = pl.from_pandas(bl.load_dataset('titanic'))
bl.tables.frequency_table(df_pl['sex'])     # works transparently
bl.quality.data_profile(df_pl)              # works transparently
