collinearity: Calculate measures of collinearity

In mosaicModel: An Interface to Statistical Modeling Independent of Model Architecture

Description

Calculate measures of collinearity

Usage

collinearity(formula, data, format = c("SeIF", "degrees", "radians", "VIF"))

Arguments

formula	a formula giving, on the right-hand side, the explanatory variables to be considered. Iteractions, etc. may also be specified.
data	a data frame from which to draw the variables in the formula
format	choice of "SeIF" for inflation of standard errors, "degrees" or "radians" for collinearity described as an angle or "VIF" for the variance inflation factor (which is the square of SeIF).

Examples

collinearity( ~ cyl * disp * hp, data = mtcars)
collinearity( ~ cyl * disp * hp, data = mtcars, format = "degrees")
