Aggregate Variable Importance Estimates

This function aggregates variable importance estimates over trees. It is a helper function used when print() is called on a variable importance estimate from a SEM forest.

aggregateVarimp(
  vimp,
  aggregate = c("mean", "median"),
  scale = c("absolute", "relative.baseline"),
  omit.na = TRUE
)

Arguments

vimp

Variable importance estimate from a SEM forest.

aggregate

Character. Either 'mean' or 'median' as function to aggregate estimates over a forest

scale

Character. Either 'absolute' or 'relative'.

omit.na

Boolean. By default TRUE, which ignores NA estimates when aggregating. Otherwise they are interpreted as zero.
