## Installation
### Conda (Recommended)
```bash
conda install -c conda-forge statista
```
### PyPI
```bash
pip install statista
```
### Development Version
```bash
pip install git+https://github.com/Serapieum-of-alex/statista
```
## Main Features
### Statistical Distributions
- **Probability Distributions**: GEV, Gumbel, Normal, Exponential, and more
- **Parameter Estimation Methods**: Maximum Likelihood (ML), L-moments, Method of Moments (MOM)
- **Goodness-of-fit Tests**: Kolmogorov-Smirnov, Chi-square
- **Truncated Distributions**: Focus analysis on values above a threshold
### Extreme Value Analysis
- **Return Period Calculation**: Estimate extreme events for different return periods
- **Confidence Intervals**: Calculate confidence bounds using various methods
- **Plotting Positions**: Weibull, Gringorten, and other empirical distribution functions
### Sensitivity Analysis
- **One-at-a-time (OAT)**: Analyze parameter sensitivity individually
- **Sobol Visualization**: Visualize parameter interactions and importance
### Statistical Tools
- **Descriptive Statistics**: Comprehensive statistical descriptors
- **Time Series Analysis**: Auto-correlation and other time series tools
- **Visualization**: Publication-quality plots for statistical analysis
## Quick Start
### Basic Usage
```python
import pandas as pd
from statista.distributions import Distributions
# Load your time series data
data = pd.read_csv("your_data.csv", header=None)[0].tolist()
# Create a distribution object (e.g., Gumbel)
dist = Distributions("Gumbel", data)
# Fit the distribution using maximum likelihood
params = dist.fit_model(method="mle")
print(params)
# Calculate and plot the PDF and CDF
pdf = dist.pdf(plot_figure=True)
cdf, _, _ = dist.cdf(plot_figure=True)
# Perform goodness-of-fit tests
ks_test = dist.ks()
chi2_test = dist.chisquare()
# Create a probability plot with confidence intervals
fig, ax = dist.plot()
```
### Extreme Value Analysis
```python
from statista.distributions import GEV, PlottingPosition
# Create a GEV distribution
gev_dist = Distributions("GEV", data)
# Fit using L-moments
params = gev_dist.fit_model(method="lmoments")
# Calculate non-exceedance probabilities
cdf_weibul = PlottingPosition.weibul(data)
# Calculate confidence intervals
lower_bound, upper_bound, fig, ax = gev_dist.confidence_interval(plot_figure=True)
```
