First, you can use a numerical search procedure to propose and evaluate different values of m and b, ultimately settling on estimates producing the least squared error.

第一种方法，可以使用数值搜索过程设定不同的m和b值并对它们求值，最终决定产生最小方差的估计值。

The estimators, m and b, that satisfy the least-squared-error criterion can be found in two basic ways.

可以用两种基本方法来找到满足最小方差法的估计值m和b。

They divide by n-1 to make it an unbiased estimator of the population variance, but I'm just going to show it in a simple way here.

当除以n-1表示的是对总体的,无偏估计,我在这里只是说的简单一点
