چکیده

A new notion of probability logical consequence is introduced. Given a probability algebra of propositions hL, P i, proposition ψ of L is called probability logical consequence of φ1 ∈ L and φ2 ∈ L (written φ1,φ2 ° ψ) iff P (ψ |φ1∧φ2 ) > max {P (ψ |φ1 ) , P (ψ |φ2 )}. A new definition of stochastic transitivity is put forward in terms of probability logical consequence. An empirical binary relation  is called stochastically transitive if a  b, b  c ° a  c. It is proved that a composition of a linear (or strictly linear) order and an independent binary random noise is stochastically transitive.

A generalization of stochastic and fuzzy transitivity for reciprocal fuzzy relations

b) moderate stochastic transitivity: For a reciprocal fuzzy relation Q : x2 + [O, 11 on a finite set of alternatives X , we introduce the concept of U-transitivity which is based upon the ordering of the matrix elements qij, qjk and qki of Q for all triples of indices i, j and k. We show that U-transitivity generalizes both stochastic and fuzzy transitivity. The U-transitivity of the secalled u...

Efficient Simulation of a Random Knockout Tournament

We consider the problem of using simulation to efficiently estimate the win probabilities for participants in a general random knockout tournament. Both of our proposed estimators, one based on the notion of “observed survivals” and the other based on conditional expectation and post-stratification, are highly effective in terms of variance reduction when compared to the raw simulation estimato...

Incompatible Stochastic Processes and Complex Probabilities

[ The definition of conditional probabilities is based upon the existence of a joint A probability. However, a reconstruction of the joint probability from given conditional probabilities imposes certain constraints upon the latter, so that if several condit.iomd probabilities are chosen arbitrarily, the corresponding joint probability may not exist, Such an incompleteness in conditional probab...

The Concept of Sub-independence and Its Application in Statistics and Probabilities

 Many Limit Theorems, Convergence Theorems and Characterization Theorems in Probability and Statistics, in particular those related to normal distribution , are based on the assumption of independence of two or more random variables. However, the full power of independence is not used in the proofs of these Theorems, since it is the distribution of summation of the random variables whic...

In Defense of a Contextualized Suppositional Account of Conditional Credence

Conditional credence is an important concept in many areas of philosophy. However, little consensus has been achieved regarding to its semantics and ontology. In this thesis I shall sketch a contextualist suppositional account of conditional credence by drawing insights from two seemingly disjoint debates: the foundational debate on the relationship between conditional and unconditional probabi...
