Logistic Regression
Fit a Logistic Regression (Logit model) of whether dependent_ticker’s return is positive on independent_tickers.
Also known as: logit model, logit regression.
For more information about the method, see regression_model.get_logistic_regression.
Logistic Regression in Python
Install the Finance Toolkit with:
pip install financetoolkit -U
Then call get_logistic_regression as shown below.
from financetoolkit import Toolkit
toolkit = Toolkit(["AAPL", "MSFT"], api_key="FINANCIAL_MODELING_PREP_KEY")
# AAPL (the first ticker) is dependent; MSFT and Benchmark are independent
toolkit.econometrics.get_logistic_regression(
independent_tickers=["MSFT", "Benchmark"], period="weekly"
)
Which returns:
| Coefficient | Std. Error | z-Statistic | P-Value | |
|---|---|---|---|---|
| Intercept | 0.0909 | 0.2195 | 0.4139 | 0.6789 |
| MSFT | 24.8481 | 10.1178 | 2.4559 | 0.0141 |
| Benchmark | 63.677 | 15.5493 | 4.0952 | 0 |
Parameters
The function accepts the following parameters:
- dependent_ticker (str | None, optional): The dependent asset (whose up/down direction is predicted). Defaults to None, meaning the Toolkit instance’s first ticker.
- independent_tickers (str | list[str] | None, optional): The independent
(predictor) asset(s). Defaults to None, meaning every other ticker in
the Toolkit instance besides
dependent_ticker. - include_benchmark (bool, optional): Whether to include “Benchmark” in the default independent ticker(s) (has no effect when independent_tickers is given explicitly). Defaults to False.
- period (str, optional): The data frequency (daily, weekly, monthly, quarterly, or yearly). Defaults to “daily”.
- column (str, optional): The historical data column to derive returns from. Defaults to “Return”.
- add_constant (bool, optional): Whether to include an intercept. Defaults to True.
- rounding (int | None, optional): The number of decimals to round the results to. Defaults to None.
