According to the possible risk levels and confidence coefficient, the risk evaluation results of water inrush are listed in Table 7.
The probabilities of risk grade indicate that the risk evaluation results are also influenced by the confidence coefficients. While the confidence coefficient selects different value, the risk evaluation result may be different.
[H.sub.1]: the coverage probability is lower than the expected confidence coefficient (CP < C[P.sub.0]),
where CP is the coverage probability, [??]P is the coverage probability estimated from this study, C[P.sub.0] is the expected confidence coefficient, and m is the repeated time.
Indeed, the residual (estimation error) formed by an adequate observer tends to zero, and the corresponding confidence coefficient increases with the decrease of confidence coefficients for other technical states.
In order to obtain the confidence coefficients {[K.sub.i] | i = [bar.0, N]}, first, we determine the characteristics called generalized membership degrees {[[??].sub.i] | i = [bar.0, N] of the technical state of the diagnosed system to each of the possible fuzzy technical states.
Indeed, an upper confidence bound of confidence coefficient CL has the form,
Regulators, policyholders, investors and managers are extremely concerned with estimating and predicting the probability of insolvency of an insurer and confidence intervals would provide them better tools for monitoring the insolvency event.(4) Selecting a confidence interval and its confidence coefficients, and deriving optimal levels of variables are also useful to insurers and other users of financial statements for controlling the risk associated with measuring the probabilities of other hazards including catastrophic losses and market crashes.
However, in the present study, these two methods showed very similar confidence coefficient and were thus considered as with the same performance ("Good").
Criteria to interpret the confidence coefficient "c" Confidence Classification (1) coefficient "c" > 0.85 Excellent 0.76 to 0.85 Very Good 0.66 to 0.75 Good 0.61 to 0.65 Intermediate 0.51 to 0.60 Tolerable 0.41 to 0.50 Poor < 0.40 Very Poor (1) Camargo & Sentelhas (1997) Table 2.
Here, [sigma] in the confidence coefficient was 0.05 and the compensation degree was 0.6.
