I keep getting the following warning when I run the efficiency test in Sawtooth:
**Warning: We strongly encourage you to further investigate the efficiency of your design prior to fielding this study.
However, I have taken steps to improve the efficiency of the design and the standard errors are well below the recommended .05 for main effects and .1 for interaction effects.
Is there something I am missing? Or does the warning just show up anytime you include a prohibition?
