    Relative Coarse-Graining.Jean-Paul Marchand - 1977 - Foundations of Physics 7 (1-2):35-49.
    The problem of statistical inference based on a partial measurement (“coarse-graining”) requires the specification of an a priori distribution. We reformulate the ordinary theory such as to encompass systematically a wide range of a priori distributions (“relative coarse-graining”). This is done in a mathematical setting which admits an interpretation in both classical probability and quantum mechanics. The formalism is illustrated in a few simple examples, such as the die whose geometrical shape is known, the spin in thermal equilibrium with an (...)

    A Minimal Phenomenology for Decay and Resonance.Jean-Paul Marchand - 1997 - Foundations of Physics 27 (2):215-226.
    We discuss in what sense the decay-scattering system is a minimal phenomenological theory for particle decay and resonance scattering.

    Statistical Inference and Quantum Mechanical Measurement.Rodney W. Benoist, Jean-Paul Marchand & Wolfgang Yourgrau - 1977 - Foundations of Physics 7 (11-12):827-833.
    We analyze the quantum mechanical measuring process from the standpoint of information theory. Statistical inference is used in order to define the most likely state of the measured system that is compatible with the readings of the measuring instrument and the a priori information about the correlations between the system and the instrument. This approach has the advantage that no reference to the time evolution of the combined system need be made. It must, however, be emphasized that the result is (...)
