This paper presents evidents that cash-flow volatility is negatively related to firm value using a large sample consisting of 2724 firm-year observations from 1998-2008.───本文通过1998-2008年间2724例公司年样本观察值证明现金流波动率与公司价值显著负相关。
The population mean is often written "x-bar." If you have a sample with n observations, it's the summation i = 1 to n of xi/n--that's the average.───人口均值经常写成“x-条形柱”,如果你有一个样本有n个观测者,是从 i=1到n和的xi/n,这是平均值。
Consider a set of observations (also called features, attributes, variables or measurements) for each sample of an object or event with known class y.───设观测向量x(也被称作特征、属性、变量、测量值等)对于对象或事件的每一个采样的所属类y都是已知的。
In the classic econometrics the sample observations are cross sectional data or time series data.
