Hi There,
This might be a stupid question, but are the 0 levels in the NGene design output for effects coded variables the base level (eg: -1) for subsequent data analysis (in Nlogit).
Cheers
Tracey

Blocking efficient designs
Hi there,
Just wondering if it is theoretically okay to block an efficent design; I have scribbled down from the course that blocking is technically only relevant for orthogonal designs. However for cost and practical reasons I would like to reduce the number of choice sets seen and am reluctant to ...
