均值(Mean):是指一组数据的平均值,是一种位置衡量指标,用来表示这些值在衡量标尺上居中的位置。在统计术语中,一个随机变量的平均值通常被称为期望值(Expectation)。方差(Variance):是指每个变量值与其均值之间的距离的平方和的均值,用一种离散程度的衡量指标,用来表示一组数据靠近其均值的程度,较小的方差表明该组...

For cost estimation, simple regression differs from multiple regression in that simple regression uses only A. One dependent variable, while multiple regression uses all available data to estimate the cost function. B. Dependent variables, while multiple regression can use both dependent and independent...
Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.
