Confronting Particle Emission Scenarios with Strangeness Data
We show that a hadron gas model with continuous particle emission instead of freeze-out may solve some of the problems (high values of the freeze-out density and specific net charge) that one encounters in the latter case when studying strange particle ratios such as those from the experiment WA85. This underlines the necessity to understand better particle emission in hydrodynamics to be able ...
متن کاملConfronting Models with Data
APRIL 2003 AMERICAN METEOROLOGICAL SOCIETY | T he use of data to evaluate models is fundamental to science. Ideally, evaluations can be controlled and optimized in the laboratory; in most cases, however, atmospheric scientists have to perform model–data intercomparisons by taking advantage of the uncontrolled opportunities that nature provides. A model-evaluation project is complicated in at le...
متن کاملConfronting Dark Energy Models with Astrophysical Data
We discuss fits of cosmological dark energy models to the available data on high-redshift supernovae and baryon oscillations. We consider a conventional model with Cold Dark Matter and a cosmological constant (ΛCDM), a model invoking super-horizon perturbations (SHDM) and models based on Liouville strings in which dark energy is provided by a rolling dilaton field (Q-cosmology). The two main hi...
متن کاملConfronting the economic model with the data
Econometrics is about confronting economic models with the data. In doing so it is crucial to choose a statistical model that not only contains the economic model as a submodel, but also contains the data generating process. When this is the case, the statistical model can be analyzed by likelihood methods. When this is not the case, but likelihood methods are applied nonetheless, the result is...
متن کاملConfronting two-sex demographic models with data.
Most population dynamics models explicitly track the density of a single sex. When the operational sex ratio can vary, two-sex models may be needed to understand and predict population trajectories. Various functions have been proposed to describe the relative contributions of females and males to recruitment, and these functions can differ qualitatively in the patterns that they generate. Whic...
