Constant Variable Situation Set Command Deductive Reasoning of Poisson Distribution
Shumin Chen · 1999
This paper illustrates a kind of constant variable situation set from the probability theory. In the time zone of length as “τ”(t,t+τ), the poisson distribution is the command of change quantity Φ(τ,t) V k(τ,t)=e -Φ(τ,t) Φ(τ,t) kk!,k=0,1,2,… Φ(τ,t)=∫ τ 0λ(t+μ) d μ The significante of the research is to find out the best plan value in the practice use on the base of the theory, so that the best benfits from it can be obtained.
