Because of a high degree of colinearity
between BM and age (Pearson correlation: r > 0.
In addition, the new system is designed to offer 80nm colinearity
In theory, colinearity
could have hampered the multivariable model.
Condition indexes and variance decomposition proportions were used to test colinearity
among the independent variables and identify the sources of colinearity
All covariates were checked for colinearity
, and those found to be correlated with one another were evaluated separately in the models to determine which were the best predictors.
In order to avoid the potential colinearity
problems from the inclusion of [[r.
To avoid the effects of colinearity
, variables that were highly correlated were not entered into the regression models simultaneously.
Outpatient facility characteristics were added singly to the final model because of colinearity
between these characteristics.
To avoid problems associated with colinearity
, we performed a correlation analysis to identify pairs of predictor variables that had high colinearity
([absolute value of r] [greater than or equal to] 0.
29), thus making it difficult to rule out the effect of colinearity
in these studies.
The issues we have highlighted here--temporal relationships between stressors and pollution; nonlinearity and saturation effects; spatial colinearity
across exposures; age-related susceptibility and critical periods; and distinctions between processes related to illness etiology and exacerbation--will be critical in exploring social--environmental interactions.
Estimates are imprecise and sensitive to subsample specifications due to substantial colinearity
