Change - point tests of location parameter and its approximate distribution 位置參數(shù)變點的非參數(shù)檢驗及其漸近性質(zhì)
It is proved that as the number of insured tends to infinity the average prospective loss random variable of this portfolio tends in probability to a certain random variable of which the approximate distribution function is derived 證明了當(dāng)保單數(shù)趨于無窮多時,平均損失變量按概率收斂于某一個隨機(jī)變量,推導(dǎo)得到了該隨機(jī)變量的近似分布函數(shù)。
Finally , we present the approximate distribution of trapping potential of the guided cold atoms in the atomic funnel based on the vccc or the uccc . by using a similar method in the analysis of optical coherence , we study the coherent evolution of the ground - state wave function of ultra - cold atoms in atomic funnel , and obtain some normalized correlation functions of the first , second , third and high order 最后,給出了原子在基于v -型和u -型載流導(dǎo)體構(gòu)建的原子漏斗中所感受到的囚禁勢的摘要采用漂流導(dǎo)體的原子易引及其原于光學(xué)器件近似分分,并采用類似于光場相干性的分析方法,計算了超冷原子物質(zhì)波的基進(jìn)波函數(shù)及其在原子漏斗中傳播時相干性的演化,得到了物質(zhì)波的一階、二階、三階和高階相于度。
