Distribution Analyser is a Web App that allows you to interactively explore continuous distributions from SciPy and fit distribution(s) to your data. Open the app in Streamlit and explore online, or clone repo and explore locally.
How to use
Here is a link to YouTube for Distribution Analyser walkthrough. http://www.youtube.com/watch?v=6S0b7gFY36I
Main options:

- Histogram
- CDF (with option P(X<=x))
- SF
- Boxplot
- Quantiles (1, 2, 3)
- Regions of 1/2/3 σ
- Generate table with statistics
Export
-
- Generate python code with your selected distribution and it's paramteters
-
- Copy code to clipboard or Download .py file and run it locally
Fit distributions
-
- This part of the app fits selected distribution(s) to the data
-
- Import your data in a .csv file, or download sample data
- Choose distribution (multiselect box), has options All_distributions
-
- Show results:
-
- Interactive Figures (limited to 15 best fits)
- Displays results in a Table (for all distributions), which can be exported as .csv file
- Generates Python code set up with the best fit distribution: makes figure with pdf, cdf and sf
