The capabilities that keep people paying for GraphPad Prism.
Guided analyses for lab data
Wizards for t-tests, ANOVA, survival and dose-response work that explain each choice.
Nonlinear regression with a model library
Built-in curve models, model comparison and parameter constraints without writing code.
Graphs linked to data tables
Journal-style graphs that update automatically when data or analyses change.
One project file for data, results and graphs
Prism's PZFX project format is proprietary, and its guided-analysis defaults are what reviewers and lab groups already expect to see.
Each covers part of the job. None replaces GraphPad Prism yet.
Partial: Point-and-click statistics on R; curve fitting is limited and graphs are basic.
Partial: Point-and-click tests with Bayesian options; no curve-fitting model library.
Partial: Covers the analyses and graphs with code; no point-and-click workflow.
