WebIn physics, a continuous spectrum usually means a set of achievable values for some physical quantity (such as energy or wavelength), best described as an interval of real numbers. It is the opposite of a discrete spectrum, a set of achievable values that are discrete in the mathematical sense where there is a positive gap between each value. kids playing with puttyWebOct 23, 2013 · For discretely valued character traits—such as the presence or absence of a feature, or the number of elements in a serially repeated structure—the prevailing method of ancestral state reconstruction uses a model of evolution in which phenotypic changes accrue under a continuous-time discrete-state Markov process (Pagel 1994, 1999; … kids playing with shaving creamWebDiscretion.
