摘 要: 本文用误差估计方法,在给定误差限和置信概率的条件下,解出了汉字字频统计的抽样规模,解出了一种汉字字频统计的抽样规模,提出了一种汉字字频统计的新方法,该方法中所定义的汉字的统计频率具有统计学上的无偏性且较之以前方法具有更小的方差。 In this paper,the lower Limit of the sample size in frequency statistics of chinese characters is given by using the method named error estimate under the conditions of giving the error bounds and the confident probability, a new statistical method of frequencies of chinese characters is presented in which the defined statisfical frequency of a chinese character is unbiased and has a smaller variance than before and therefore is a preciser estimate of utility frequency of the chinese character.
