摘要
应用二项分布的参数极大似然估计法 ,计算地层中化石属种数目的估计值 ,得出在彼此相距不远的n个或可列个剖面上取样的一般估计式 :NΛ =r(s1 +s2 +ΛΛ +sn)k1 +k2 +ΛΛ +kn。通过实例检验其有效性的基础上 ,从理论上提出诸如此类的统计数学模型。
s: In this paper, the author calculates the approximation of the fossite's genus and species in Stratum by use of the two-term distribution of maximum likelihood mathematical method; concludes this common formula NΛ=[r(s_1+s_2+ΛΛ+s_n)k_1+k_2+ΛΛ+k_n] that how to collect the sample on the nearby section. And based on its effictivity, the author establishes the statistical mathematical methods for the analogous things.
