Value

A reordered version of d.

Examples

f <- lm(Sepal.Length ~ ., data = iris[, -5])
m <- vivi(fit = f, data = iris[, -5], response = "Sepal.Length")
#> Agnostic variable importance method used.
#> Calculating interactions...
corimp <- abs(cor(iris[, -5])[1, -1])
viviUpdate(m, corimp) # use correlation as importance and reorder
