The prior probability P[(u, v, w)|S[C.sub.k]] can be approximately calculated through Formula (15):
Actually, [3] takes the prior probability Pr([c.sub.i]) as an approximation of the posterior probability Pr([c.sub.i] | r).
According to the framework Lindley presents, a DM has prior probability [[pi].sub.0] = Pr[[H.sub.0]|I] for the proposition [H.sub.0] based on whatever information I is available to him or her apart from y and x.
Subsequently, the prior probability that a landslide surge will occur and the conditional probability that the dam will overtop due to the landslide surge were calculated for different water levels in the reservoir.
Also, the prior probability of these parameters is assumed to be Dirichlet distributed.
The "frequency" property represents the prior probability knowledge, and the "specificity" property represents a specificity value with a scale of 0-5 to represent the probability value of 0 and 1, respectively.
p(A)=the prior probability of outcome A occurring regardless of condition B
While the Neyman-Pearson approach is weakened by its own objectivity, the Bayesian approach, which infers the likelihood of an event from the combination of the prior and posterior probabilities distribution, has its main pitfalls in the subjective interpretation of prior probability because it can lead two scientists in obtaining different results starting from the same dataset.
To choose a prior, we have experimented with different prior beliefs of level-shift probability, using 0.5, 1, 2, 5, and 10% prior probability. The use of a 10% prior makes the posterior mean of shift probability closest to the prior probability.
A prior probability indicates a correct answer rate at each level on the placement test.
Then, the prior probability of cause items should be generated.
However as the prior probability of channel occupation P([h.sub.1]) changes in comparison to the probability of channel vacancy P([h.sub.0]), effects of changing priors become prominent.
