With regard to statistical characteristics of valuation multiples in the field,the paper suggests using trimmed mean rather than mean or median due to its better robust efficiency.
考虑实践中估值乘数的统计特征,分析了切尾均值及其两个极端——算术均值和中位数的耐抗性和效率稳健性,给出了适用于估值实践的简单切尾规则;建议用可比公司估值乘数的切尾均值作为目标公司估值乘数的点估计,并用自助法求得其近似置信限。
2) trimmed mean
截尾均值
