Installation

You can install the package using pip:

pip install universal-timeseries-transformer

Requirements

• Python >= 3.8
• Dependencies:
  • pandas
  • numpy

Usage Examples

1. Basic Time Series Transformation

from universal_timeseries_transformer import IndexTransformer, DataFrameTransformer
import pandas as pd

# Create sample time series data
df = pd.DataFrame({'value': [1, 2, 3, 4]},
                  index=pd.date_range('2025-01-01', periods=4))

# Transform time series index
index_transformer = IndexTransformer(df)
weekly_data = index_transformer.to_weekly()

# Apply data transformations
df_transformer = DataFrameTransformer(weekly_data)
result = df_transformer.rolling_mean(window=2)

2. Advanced Time Series Operations

from universal_timeseries_transformer import TimeseriesBasis

# Initialize time series basis
ts_basis = TimeseriesBasis(df)

# Perform complex transformations
transformed_data = ts_basis.transform()

)

Find funds with borrowings

funds_with_borrowings = search_funds_having_borrowings(date_ref='2025-02-21')

Get borrowing details

fund_code = '100075' borrowing_details = get_borriwings_by_fund(fund_code=fund_code, date_ref='2025-02-21')

### 3. Check Repo Agreements

```python
from financial_dataset_preprocessor import (
    search_funds_having_repos,
    get_repos_by_fund
)

# Find funds with repos
funds_with_repos = search_funds_having_repos(date_ref='2025-02-21')

# Get repo details for a specific fund
fund_code = '100075'
repo_details = get_repos_by_fund(fund_code=fund_code, date_ref='2025-02-21')
