R-squared can take any values between 0 to 1. Although the statistical measure provides some useful insights regarding the regression model, the user should not rely only on the measure in the assessment of a statistical model. The figure does not disclose information about the causation relations...
解析 C。选项 A 是数学符号表达,不是英语表达。选项 B“pie”拼写错误,应该是“pi”,且“square”缺少动词形式。选项 C 表达正确,“times”表示“乘以”,“squared”是“平方”的正确表达。选项 D“the square of pi r”表达不准确,应该是圆半径的平方乘以圆周率。
