An unbiased estimator is a sample statistic, which has an expected value equal to the value of the population parameter.
An unbiased estimator is a sample statistic, which has an expected value equal to the value of the population parameter.
A point estimator will be unbiased if the A: expected value of the point estimator equals the value of the population parameter B: sample size is greater than 30 or np ³ 5 and n(1-p) ³ 5 C: sampling distribution is normally distributed D: value of the population parameter is known

allows the effect of changing one of the binary independent variables to depend on the value of the other binary variable. A: occurs when a selection process influences the availability of data and that process is related to the dependent variable. B: is only important for finite sample results. C: results in the OLS estimator being biased, although it is still consistent. D: is more important for nonlinear least squares estimation than for OL
