Hi guys,
I have a situation where an additive model is the most supported model for detection. One of my covariates in this model is temperature and its influence on detection is quite strong when the other covariate is held constant for all sites. However, the other categorical covariate (detector type) appears to not have any influence on detection when temperature is held at its mean. Just wondering why detector type comes out as being supported in an additive model when it doesn't appear to influence detection on its own?
Cheers,
Leroy.
