Limits on noncommuting extended technicolor.

Using precision electroweak data, we put limits on noncommuting extended technicolor models. We conclude that these models are viable only if the ETC interactions are strong. Interestingly, these models predict a pattern of deviations from the standard model which can fit the data significantly better than the standard model does, even after taking into account the extra parameters involved. {copyright} {ital 1996 The American Physical Society.}
