算法和有意思的小问题都可以。


做小组作业，活都被队友分了，我没东西可以做了，又必须做（自己也很想做）

已经用了hessain和Fisher scoring两种


If r, p, q are gene frequencies of O, A, B respectively in the population.  

Given observed counts nO,nA,nB,nAB, implement a program in R to compute the maximum likelihood
estimates of p, q, r using the Fisher scoring and the Newton-Raphson methods.
