Cards

Term
asymptotic bias
Definition
the difference between the probability limit of an estimator and the parameter value
Term
asymptotic confidence interval
Definition
a confidence interval that is approximately valid in large sample sizes
Term
asymptotic normality
Definition
the sampling distribution of a properly normalized estimmator converges to the standard normal distributions
Term
asymptotic properties
Definition
properties of estimators and test statistics that apply when the sample size grows without bounds
Term
asymptotic standard error
Definition
a standard error that is valid in large samples
Term
asymptotic t statistics
Definition
a t statistic that has an approximate standard normal distribution in large samples
Term
asymptotic variance
Definition
the square of the value by which we must divide an estimator in order to obtain an asymptotic standard normal distribution
Term
asymptotically efficient
Definition
for consistent estimators with asymptotically normal distributions, the estimator with the smallest aymptotic variance
Term
auxiliary regression
Definition
a regression used to compute a test statistic - such as the test statistics for heteroskedasicity and serial correlation - or any other regression that does not estimate the model of primary interest
Term
consistency
Definition
an estimator converges in probability to the correct population value as the sample size grows
Term
inconsistency
Definition
the difference between the probability limit of an estimator and the parameter value
