For a given sample size,the bias in 1β% increases as x increases (holding the sum of the 2ix fixed).But as x increases,the variance of 1 βincreases relative to Var(1β%).The bias in 1β% is also small when 0β is small.Therefore,whether we prefer 1β% or 1 β on a mean squared error basis depends on the sizes of 0β,x,and n (in addition to the size of 21niix=∑).

对于一个给定的样本大小,在1β％上升为x的增加持有固定2ix总和（偏差）.但为x的增加,1βincreases方差相对瓦尔（1β％）.在1β％偏差也很小很小的时候0β.因此,无论我们喜欢上均方误差的基础上1β或1％β取决于0β的大小,x和n的除了21niix =∑大小（）.
