我已研究如何产生两种随机内.,其面积为%(即样本总数为N),但似乎通常有偏见。

Is there a better (and preferably simpler) way to generate random numbers between 0 and n (number of samples)?

n 取自载有数据点清单的档案。 目的是通过应用RASAC的数据来设计一条线。

最佳回答

<编码>rand() % n,在<代码>n<>/code>上,仅使用随机编号的低比值,大大小于RAND_max/code>。 最好使用所有轨道,例如通过RAND_import/code>将(floating point)号码在0.0至1.0之间,然后乘以n,并改换为ger。

《<代码>rand(<>>>>>>>的实施也不可能对一些用途来说不够好。 在这种情况下,完全使用另一个随机生成器(例如Mersenne Twister)。
