查询词典 distributions

We find in form, the surface parts which are put in front of the time marks of the two structures are antithetic of affirmation and negation; in content, these two structures fully show their complementary distributions with their process meaning and critical meaning. And the essence of the complementary distributions is the contradiction of one-way dimension of objective time and inverse subjective thought.

For this type of new model,we study it mainly from these ways:First,we make further research on the nature features of their distributions;give out the probability distribution of the mixed stochastic variables,and the statistical features and the approximate distributions of the short-term individual risk models. Also the relationships between the total amount of compound compensation and individual one were investigated.At last we give out a kind of practical calculation method for the individual risk model.That is the calculation of the number of claims translating into the calculation of Vandermonde determinant.Second,a kind of risk model with main claims and by-claims is built under specific conditions.
