Predict Method for Regression Conformal Objects

Generate prediction intervals for new data using a fitted conformal prediction object.

Usage

# S3 method for class 'predictset_reg'
predict(object, newdata, ...)

Arguments

object

A predictset_reg object.

newdata

A numeric matrix or data frame of new predictor variables.

...

Additional arguments. For Mondrian objects, pass groups_new (a factor or character vector of group labels for each observation in newdata). For weighted conformal objects, pass weights_new (importance weights for each row of newdata).

Value

A data frame with columns pred, lower, and upper.

Examples

set.seed(42)
x <- matrix(rnorm(200 * 3), ncol = 3)
y <- x[, 1] * 2 + rnorm(200)
x_new <- matrix(rnorm(10 * 3), ncol = 3)

result <- conformal_split(x, y, model = y ~ ., x_new = x_new)
preds <- predict(result, newdata = matrix(rnorm(5 * 3), ncol = 3))
