6) expected frequency
期望频率

Based on the occurrence frequencies of oligonucleotides in the non-coding sequences of yeast genes, some over-represented oligonucleotides are extracted in the introns of high-transcribed yeast genes by expected frequency method.
基于酵母基因非编码序列中寡核苷酸的出现频率 ,拟用期望频率法从转录效率较高的内含子序列中提取到一些过表达的寡核苷酸。
补充资料：期望
①对未来情况寄托希望或有所等待：期望能有成功的一天。②又称“数学期望”、“均值”。概率论的基本概念。指随机变量ξ取值的加权平均数，其权数就是相应的概率或概率密度，常以eξ表示。期望由它的概率分布唯一确定，它反映了随机变量取值的平均，是随机变量最重要的数学特性。
