- Depends on test statistics
- Sometimes true
- False
if the residuals from a regression estimated using a small sample of data are not
Select one:
- The coefficient estimate will be biased inconsistent
- The coefficient estimate will be biased consistent
- Test statistics concerning the parameter will not follow their assumed distributions
- The coefficient estimate will be unbiased inconsistent

The coefficient of determination, r squared shows
Select one:
- Proportion on the variation in the dependent variable error term is explained by the independent variable X
- Proportion of the variation in the dependent variable X is explained by the error term
- Proportion of the variation in the dependent variable Y is explained by the independent variable X
- Proportion of the variation in the dependent variable X is explained by the independent variable Y
If multicollinearity is perfect in a regression model then the regression coefficients of the explanatory variables are
Select one:
- Indeterminate
- Infinite values
- Determinate
- Small negative values
Multicollinearity is limited to
Select one:
- Cross-section data
- Pooled data
- cross-section data, time series data and pooled data
- Time series data
If there exist high multicollinearity, then the regression coefficients are
Select one:
- Indeterminate
- Infinite values
- Determinate
- small negative values
What will be the properties of the OLS estimator in the presence of multicollinearity?
