Arguments

fit

object of class \'MetaForest\'.

newdata

new data with the same columns as the data used for fit

Value

an n x n matrix where position i, j gives the proportion of times observation i and j are in the same terminal node across all trees.

Examples

# \dontshow{ set.seed(42) data <- SimulateSMD(k_train = 100, distribution = "bernoulli", model = es * x[,1]*x[,2]) #Conduct unweighted MetaForest analysis mf.unif <- MetaForest(formula = yi ~ ., data = data$training, whichweights = "unif", method = "DL") prox_matrix <- extract_proximity(mf.unif) # }
