Phitter is an open-source Python library designed to streamline the process of fitting and analyzing probability distributions for applications in statistics, data science, operations research, and machine learning. It provides a comprehensive catalog of over 80 continuous and discrete distributions, multiple goodness-of-fit measures (Chi-Square, Kolmogorov-Smirnov, and Anderson-Darling), interactive visualizations for exploratory data analysis and model validation, and detailed modeling guides with spreadsheet implementations. By reducing the complexity of distribution fitting, Phitter helps researchers and practitioners identify distributions that best model their data.[1][2][3]

Features

[edit]

Phitter supports fitting over 80 continuous and discrete probability distributions and includes the following features:

  • Documentations, spreadsheets and python support for continuous and discrete distributions[4]
  • Web-based interface and Python library[5]
  • Goodness-of-fit tests: Chi-square, Kolmogorov–Smirnov, Anderson–Darling[6]
  • Interactive visualizations: PDF overlays, CDF plots, Q–Q plots[7]
  • Automated modeling reports with formulas and parameter estimates
  • Simulation tools for stochastic processes and queueing systems (e.g., FIFO, LIFO)
  • Parallel processing for large datasets
  • Open-source under the MIT License
