regressors造句

• Technically, it is more difficult to derive the sign of omitted variable bias with multiple regressors
  从技术上讲，要推出多元回归下缺省一个变量时各个变量的偏误方向更加困难。
• Exception : if the new regressor is perfectly multicollinear with the original regressors, then ols cannot be implemented
  例外：如果这个新解释变量与原有的解释变量完全共线，那么ols不能使用。
• If we suspect that hsk depends only upon certain regressors, we can modify the bp test to regress residuals from step 1 on those regressors and carry out the appropriate f or lm test
  如果我们怀疑hsk仅依赖与某些特定的解释变量，我们可以做一些调整：将第一步的残差只对那些解释变量回归，并进行适当的f或lm检验。
