Population predictions from a NLME model

Description

Computes population-level predictions (eta = 0) for all subjects.

Usage

ferx_predict(model, data = NULL, fit = NULL)

Arguments

  • model: Path to a .ferx model file
  • data: Path to a NONMEM-format CSV. When omitted, the model file’s [data] block (path = ...) is used. The DV column may be left empty (. / NA) on the sampling rows - PRED is what this function produces and the DV is never read, so an empty cell means “predict here”. Rows marked MDV = 1 are excluded, as always.
  • fit: Optional ferx_fit result. When provided, predictions use fit$theta instead of the model file’s initial estimate for theta.

Examples

ex <- ferx_example("warfarin")
fit <- ferx_fit(ex$model, ex$data, method = "gn", covariance = FALSE)
preds <- ferx_predict(ex$model, ex$data, fit = fit)
head(preds)
