Parameter estimates depend both on the source model and on the fitted model: An example

Distributions of estimates of the threshold for mental rotation under two fitted models were collected from computer simulations of three source models and from human data. The estimates depend both on the source of the data and on the fitted model used for parameter estimation. The concept of a source model’s “fertility” is illustrated by a characteristic of the human data shared by one of the source models. © 1988, The Psychonomic Society, Inc.. All rights reserved
