Distribution Analyser

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:

• Explore distributions - Interactively explore continuous distribution functions from SciPy v1.6.1.
• Fit distributions - Import your data and fit selected continuous distribution(s) to them.

Explore distributions

• Select distribution
• Use sliders to change distribution parameters and see how distribution changes

• Fine tunning:

  • Slider can be in steps of 0.10 / 0.01
  • Possible to enter paramter values manually

Tweak display

• Dark/Light Mode

• Figure display on/off options:

  • Histogram
  • PDF
  • 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

Use Distribution Analyser localy
