Determining Transition Probabilities

Medical Decision Making, 1994
Confusion regarding proper use of the terms rate and risk persists in the literature. This has implications for the proper modeling of prognosis and transition between health states in decision analysis and related techniques. The issue is complicated by the plethora of terms related to rate and risk. Although the suggestion to use the terms force and

Understanding transition probabilities

Linguistic Typology, 2011
Dunn et al. (2011) propose an innovative approach to establishing typological correlations. Their fascinating method exemplifies the dynamicization of linguistic typology. Instead of estimating relative frequencies of types, they switch to estimating transition probabilities between types.

Markov transition probabilities. I

Zeitschrift für Wahrscheinlichkeitstheorie und Verwandte Gebiete, 1967
A continuous-parameter Markov process on a general state space has transition function P t (x,E). The theory of regenerative phenomena is applied to the question: what functions of t can arise in this way? Particular attention is paid to processes of purely discontinuous type, to which are extended known results for ...

Transition probabilities in146Eu

Zeitschrift für Physik A Hadrons and nuclei, 1972
Transition probabilities in the odd-odd nucleus146Eu are measured. A recent determination of the lifetime of the 115.6 keV level has indicated a strong retardation of the 115.6 keVM1 transition. In contrast, the present results areT1/2(230.3)≦165 ps,T1/2(115.6)≦160 ps.

Theoretical Transition Probabilities

The Journal of Chemical Physics, 1966
The contribution to the intensity of atomic and molecular electronic transitions beyond the Hartree—Fock, or independent-particle model, is examined by means of ``many-electron theory'' (MET). The contribution is of first order in the wavefunctions of the combining states.
