ols估计量是通过()推导的:
将因变量的值扩大10,将自变量的值同时扩大100,则:
估计量具有抽样分布的原因是()
在其他因素相同的条件下,斜率估计量标准差较小,如果()
误差项的异方差会影响ols估计量的()
解释变量与残差之间的样本协方差总是为零。
回归模型 不可以用ols估计,因为它是一个非线性模型。
在经典的资本资产定价模型中,股票的超额收益率(定义为股票的收益率减去无风险收益率)是市场组合超额收益率(定义为市场大型组合收益率减去无风险收益率)的线性函数,即. 设某年的国债收益率百分之3.5,而大型分散化股票组合(s&p500)收益率为百分之7.3,如果微软公司的系数为1.27,则同期微软公司的股票收益率为百分之()。(答案保留小数点后两位)
假设某研究者基于100个班的班级规模(cs)和平均测试成绩(testscore)数据估计的ols回归为: 若某班级有22个学生,则班级平均成绩的估计值是()(答案保留小数点后两位)
假设某研究者基于100个班的班级规模(cs)和平均测试成绩(testscore)数据估计的ols回归为: 这100个班的测试成绩的样本标准差()等于( )(答案保留小数点后两位)
在回归方程 = 698.9 – 2.28 × str 中,如果斜率系数的 t- 统计量为 -4.38, 则它的标准误是()?
在假设检验中,如果得到一个很小的 p-值(比如小于5%),则
如果一个假设在5%的显著水平下不能被拒绝,则它
如果一个假设在5%的显著水平下被拒绝,则它
下列哪个现象会使得通常的ols t 统计量无效?
用小样本数据进行回归时,如果用正态分布来代替原本应该使用的t-分布来进行单个回归系数的检验会导致拒绝域的增大。
当经典线性回归模型去掉残差服从正态分布的假设时,仍然可以使用最小二乘法来估计未知参数,但是这时检验某个参数是否等于0的统计量不再服从t分布。
在一个研究工人年龄(age)对时薪(ahe)的一元回归方程中,我们得到如下的估计结果: = 1.08 0.60 ´ age (1.17) (0.04) 为了检验斜率参数的显著性,则该检验的p值为()。(答案精确到小数点后两位)
在上述研究中,假设我们分别对具有高中文凭和大学文凭的工人做回归,得到如下估计结果: 高中组: = 6.52 0.30 ´ age (1.25) (0.04) 大学组: = -4.44 0.92 ´ age (1.77) (0.06) 则大学组与高中组年龄对时薪的边际影响差异为()。(答案精确到小数点后两位)
在上述两个回归中,假设两组样本是独立的,则大学组与高中组年龄对时薪的边际影响差异的置信区间上界为()。(答案精确到小数点后两位,。提示,对于两组独立样本,)
