Figure 1: Likelihood-based methods are less accurate than maximum parsimony (MP) under heterogeneous conditions. Figure 2: Parsimony outperforms likelihood over a wide range of heterotachous ...

This example and notation are taken from Bard (1974). A two-equation model is used to fit U.S. production data for the years 1909-1949, where z 1 is capital input, z 2 is labor input, z 3 is real ...

This example calculates confidence intervals based on the profile likelihood for the parameters estimated in the previous example. The following introduction on profile-likelihood methods is based on ...
