Meta-analysis: Fixed-effect model [PDF]

open access: yesAmerican Journal of Orthodontics and Dentofacial Orthopedics, 2020
A meta-analysis, a statistical combination of data from selected studies, is implemented by choosing a priori between 2 popular statistical models: fixed-effect and random-effects models.1 The choice of the appropriate model for the analysis is critical to ensure the credibility of the results and depends on both the goals of the analysis and the

The squeeze effect in non-integrable Hamiltonian systems [PDF]

open access: yes, 1988
In non-integrable Hamiltonian systems (represented by mappings of the plane) the stable island around an elliptic fixed point is generally squeezed into the fixed point by three saddle points, when the rotation number ρ of the motion at the fixed point ...
