In some circumstances (too short Boruta run, unfortunate mixing of shadow attributes, tricky dataset...), Boruta can leave some attributes Tentative.
TentativeRoughFix
performs a simplified, weaker test for judging such attributes.
TentativeRoughFix(x, averageOver = Inf)
A Boruta class object with modified finalDecision
element.
Such object has few additional elements:
Original finalDecision
.
Copy of averageOver
parameter.
an object of a class Boruta.
Either number of last importance source runs to average over or Inf for averaging over the whole Boruta run.
Function claims as Confirmed those attributes that have median importance higher than the median importance of maximal shadow attribute, and the rest as Rejected. Depending of the user choice, medians for the test are count over last round, all rounds or N last importance source runs.
