1"""JSharpe: Sharpe Ratio Analysis and Statistical Testing. 

2 

3This package provides comprehensive tools for Sharpe ratio analysis, 

4including statistical significance testing, multiple testing corrections, 

5and portfolio optimization utilities. 

6 

7Key features: 

8 - Sharpe ratio variance estimation under non-Gaussian returns 

9 - Minimum track record length computation 

10 - Probabilistic Sharpe Ratio (PSR) calculation 

11 - False Discovery Rate (FDR) control for multiple strategy testing 

12 - Family-Wise Error Rate (FWER) corrections (Bonferroni, Šidák, Holm) 

13 - Minimum variance portfolio optimization 

14 

15Example: 

16 >>> import numpy as np 

17 >>> from jsharpe.sharpe import sharpe_ratio_variance, probabilistic_sharpe_ratio 

18 >>> # Compute variance of a Sharpe ratio estimate 

19 >>> var = sharpe_ratio_variance(SR=0.5, T=24) 

20 >>> # Compute the Probabilistic Sharpe Ratio 

21 >>> psr = probabilistic_sharpe_ratio(SR=0.5, SR0=0, T=24)
