Make Predictions from a Fitted Ensemble Partial Least Squares Model

Make predictions on new data by fitted enpls.fit object.

Usage

predict(object, newx, method = c("mean", "median"), ...)

Arguments

object

An object of class enpls.fit.

newx

New data to predict with.

method

Use "mean" or "median" to create the final prediction.

Examples

data("alkanes")
x <- alkanes$x
y <- alkanes$y

set.seed(42)
fit <- enpls.fit(x, y, reptimes = 50)
y.pred <- predict(fit, newx = x)
plot(y, y.pred, xlim = range(y), ylim = range(y))
abline(a = 0L, b = 1L)

y.pred.med <- predict(fit, newx = x, method = "median")
plot(y, y.pred.med, xlim = range(y), ylim = range(y))
abline(a = 0L, b = 1L)
