predict_maihda: Predict from MAIHDA Model

In MAIHDA: Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy

Predict from MAIHDA Model

Description

Makes predictions from a fitted MAIHDA model, either at the stratum level or individual level.

Usage

predict_maihda(object, newdata = NULL, type = c("individual", "strata"), ...)

Arguments

object	A maihda_model object from fit_maihda().
newdata	Optional data frame for making predictions. If NULL, uses the original data from model fitting.
type	Character string specifying prediction type: "individual": Individual-level predictions including random effects "strata": Stratum-level predictions (random effects only)
...	Additional arguments passed to predict method of underlying model.

Value

Depending on type:

• For "individual": A numeric vector of predicted values

• For "strata": A data frame with stratum ID and predicted random effect

Examples

strata_result <- make_strata(maihda_sim_data, vars = c("gender", "race"))
model <- fit_maihda(health_outcome ~ age + (1 | stratum), data = strata_result$data)

# Individual predictions
pred_ind <- predict_maihda(model, type = "individual")

# Stratum predictions
pred_strata <- predict_maihda(model, type = "strata")
