+#' Perform a hierarchical model fit with multiple starting values
+#'
+#' The purpose of this method is to check if a certain algorithm for fitting
+#' nonlinear hierarchical models (also known as nonlinear mixed-effects models)
+#' will reliably yield results that are sufficiently similar to each other, if
+#' started with a certain range of reasonable starting parameters. It is
+#' inspired by the article on practical identifiabiliy in the frame of nonlinear
+#' mixed-effects models by Duchesne et al (2021).
