A simple method of the maximum likelihood estimation of the number of nucleotide substitutions is presented for the case where restriction sites data from many different restriction enzymes are available. An iteration method, based on nucleotide counting, is also developed. This method is simpler than the maximum likelihood method but gives the same estimate. A formula for computing the variance of a maximum likelihood estimate is also presented.
针对可获得多种不同限制酶的限制位点数据的情况,提出了一种估计核苷酸替换数目的简单最大似然估计方法。还开发了一种基于核苷酸计数的迭代方法。该方法比最大似然方法更简单,但给出相同的估计值。同时还给出了一个计算最大似然估计方差的公式。
