R library OptimalDesign
- The library OptimalDesign
enables the user to easily compute D-, A-, I-, and c-efficient designs of experiments including:
- optimal approximate and exact designs with or without replications,
- optimal designs at standard or restricted design spaces,
- optimal designs under various kinds of simultaneous constraints, ...
can also be used to compute the solutions to some related optimization problems such as
minimum-volume data-enclosing ellipsoids and t-optimal graphs.
- The library is free, including the free academic license for the few functions that require the commercial
gurobi solver; see our gurobi installation guide.
- See a brief introduction including mathematical specifications.
- Bugs and suggestions for improvement
- We will be happy to help you with any technical or theoretical problem,
or with any question related to the computation of experimental designs.
