...	further arguments passed to or from other methods.

Value

Object of class MetaForest.prediction with elements

Examples

set.seed(56)
data <- SimulateSMD(k_train = 100, model = es * x[,1] * x[,2])
#Conduct fixed-effects MetaForest analysis
mf.fixed <- MetaForest(formula = yi ~ ., data = data$training,
                      whichweights = "fixed", method = "DL")
predicted <- predict(mf.fixed, data = data$testing)$predictions
r2_cv <- sum((predicted - mean(data$training$yi)) ^ 2)/
         sum((data$testing$yi - mean(data$training$yi)) ^ 2)
