+#' Neonatal weight progression data
+#'
+#' Longitudinal body-weight measurements for a cohort of neonates over roughly
+#' the first week of life, used as the second case study (neonatal weight
+#' progression) in Rohleff et al. (2025) on VAE-based nonlinear mixed-effects
+#' modeling. There is no dosing; body weight follows a turnover (zero-order
+#' production, first-order elimination) growth model whose initial weight is an
+#' estimated parameter, so every record is an observation (\code{EVID = 0}).
+#'
+#' @format A data frame with 1120 rows by 9 columns
+#'
+#' \describe{
+#'   \item{ID}{Subject ID (189 neonates)}
+#'   \item{TIME}{Time since birth (days)}
