# Small design-of-experiments planner
# Scope: Two-factor two-level fitted response using supplied main/interaction coefficients; no statistical fitting.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

factorA = 1
factorB = -1
intercept = 10
effectA = 2
effectB = 3
interaction = 1

response := intercept+effectA*factorA+effectB*factorB+interaction*factorA*factorB

check response budget: response <= 12

scenario alternative: factorA = 0.8
