Mass and age category were investigated in separate models because of some colinearity
The results we observed must interpreted with caution because of the small population studied and the possibility of colinearity
, since many of the variables correspond to activities with a similar potential for rodent exposure.
pylori infection, and antacid use to resolve colinearity
issues with race.
Those risk factors independently associated with the disease were evaluated in multivariate analyses by using log-binomial regression models after we ascertained the absence of a significant multiple colinearity
among the variables.
Because of the need to reduce colinearity
, we did not analyze environmental variables with similar geographic distributions together in the same model.
and interaction among variables were calculated by using standard statistical techniques.
was examined by replacing variables with each other and examining the effect on the model.
issues and sample size limit interpretation of models containing all SES and home characteristics variables, although race/ethnicity appeared to have significant associations with dust mite and cockroach levels that were independent of the other SES and home characteristics variables considered.
This creates colinearity
problems, which could be difficult to address.
We restricted all models to participants who gave usable responses to all variables (n = 7,430) and assessed models for potential 2-way interactions, goodness of fit, and potential colinearity
This introduces greater colinearity
between it and a general ideology variable such as the Nominate scores, which in turn can cause a counfounding effect upon the coefficient of the ideology variable.
4, which indicates colinearity
between these variables, were not included in the logistic regression model.
