About this app

Planned Experiment Lite is a compact environment for classical design of experiments, OLS regression and response-surface plots — from the design matrix to contours and an interactive 3D surface.

Build a plan, enter parallel measurements, fit a polynomial, test it, and find an optimum in the coded cube [−1, +1]^k. Factor coding is the textbook form: x = (X − X0) / ΔX.

WHAT THIS EDITION INCLUDES
• Plans: one-factor grid; full factorial 2^k with up to three factors.
• Up to three parallel runs per design point.
• OLS with main effects, two-factor interactions and squares; optional three-factor interactions for 2^k.
• Cochran homogeneity, Student t on coefficients, Fisher lack-of-fit. R², R²adj, RMSE.
• Drop insignificant terms and refit. Canonical analysis of the stationary point and a constrained extremum in the experimental region.
• Response curves, colour contours and an interactive 3D surface in natural units.
• PDF report and JSON of your own project. Local gallery save is always available.

This Lite edition does not include other design families, a custom matrix, or CSV export. There are no in-app purchases.

ADS
A thin banner from Yandex Advertising Network is shown at the bottom of the screen. The app may use the device advertising ID to serve ads. Experiment files stay on the device. No account is required.

WHO IT IS FOR
Researchers, process engineers, chemists, metallurgists and students who want transparent classical tests rather than a black box.

Planned Experiment Lite continues the PlanExp 2³ line. The mathematical core is shared with the iPhone, iPad and Mac apps; this build is the free Android edition for Google Play.

What’s new

Data visualization and report export have been improved.
