Installation

Prerequisites

• Python 3.8 or higher
• pip or conda package manager

Using pip

pip install statflow

Using conda

conda install -c conda-forge statflow

Usage

Basic Usage

from statflow import DataFlow, StatisticalAnalysis

# Create a data flow pipeline
flow = DataFlow()
flow.load_data("data.csv")
flow.clean_data()
flow.transform_data()

# Perform statistical analysis
analysis = StatisticalAnalysis(flow.data)
summary = analysis.descriptive_stats()
correlation = analysis.correlation_matrix()

Advanced Usage

from statflow import TimeSeries, HypothesisTest

# Time series analysis
ts = TimeSeries("time_series_data.csv")
trend = ts.decompose()
forecast = ts.predict(steps=10)

# Hypothesis testing
test = HypothesisTest(sample1, sample2)
result = test.t_test()
p_value = result.p_value
