Conformal prediction band for a single new patient

Convenience wrapper around split-conformal conformalInterval() for one new observation, returning the guaranteed-coverage predicted band.

Usage

conformalPredict(model, calib, newx, alpha = 0.1, seed = NULL)

Arguments

model

A fitted model (see conformalInterval()).

calib

The calibration data frame (response + predictors).

newx

A one-row data frame of predictors for the new patient.

alpha

Miscoverage level (default 0.1).

seed

Optional integer random seed.

Value

An AnalysisResult with type = "conformal" for the single patient.

Examples

set.seed(1)
d <- data.frame(x = rnorm(80)); d$y <- 1.5 * d$x + rnorm(80)
fit <- lm(y ~ x, data = d[1:40, ])
conformalPredict(fit, d[41:80, ], data.frame(x = 0.5))
