probability interval
2.As for statistical estimation, the existence of MEPI will reduce the confidence probability when confidence interval is maintained.
3.Accordng to Gaussian distribution equation, we can paint a curve and obtain the normal distribution curve of random error and the rule of random error. According to the rule, we may get probability of random and confidence interval.
4.In this paper it is proved that there are no scramble sets with nonzero invariant probability measure and especially there are no sequence-distribution-scramble sets with nonzero invariant probability measure in the minimal mappings of a compace metric space and interval mappings with zero topological entropy.
5.Since the probability density function of chaotic sequence for Kent map is the uniform function on interval (0,1), the hybrid chaos optimization-BFGS algorithm is established on basis of Kent map.
