Newey]] and [[Kenneth D. West]] in 1987, although there are a number of later variants.<ref>{{Cite journal \| doi = 10.2307/1913610 \| last1 = Newey \| first1 = Whitney K \| last2 = West \| first2 = Kenneth D \| year = 1987 \| title = A Simple, Positive Semi-definite, Heteroskedasticity and Autocorrelation Consistent Covariance Matrix \| jstor = 1913610\| journal = Econometrica \| volume = 55 \| issue = 3\| pages = 703–708 }}</ref><ref>{{Cite journal \| doi = 10.2307/2938229 \| last1 = Andrews \| first1 = D.W.K. \| year = 1991 \| title = Heteroskedasticity and autocorrelation consistent covariance matrix estimation \| jstor = 2938229\| journal = Econometrica \| volume = 59 \| issue = 3\| pages = 817–858 }}</ref><ref>{{Cite journal \| doi = 10.2307/2297912 \| last1 = Newey \| first1 = Whitney K. \| last2 = West \| first2 = Kenneth D. \| year = 1994 \| title = Automatic lag selection in covariance matrix estimation \| jstor = 2297912\| journal = Review of Economic Studies \| volume = 61 \| issue = 4\| pages = 631–654 }}</ref><ref>{{Cite journal \| last1 = Smith \| first1 = Richard J. \| year = 2005 \| title = Automatic positive semidefinate HAC covariance matrix and GMM estimation \| url = \| journal = Econometric Theory \| volume = 21 \| issue = 1\| pages = 158–170 \| doi = 10.1017/S0266466605050103 }}</ref> The estimator is used to try to overcome [[autocorrelation]], or [[correlation]], and [[heteroskedasticity]] in the [[errors and residuals in statistics\|error terms]] in the models. This is often used to correct the effects of correlation in the error terms in regressions applied to [[time series]] data.

			The problem in autocorrelation, often found in time series data, is that the [[error term]]s are correlated over time. This can be demonstrated in <math>Q</math>, a matrix of [[sums of squares]]{{dn\|date=December 2013}} and cross products that involves <math>\sigma_{(ij)}</math> and the rows of <math>X</math>. The least squares estimator <math>b</math> is a [[Consistent estimator\|consistent]] estimator of <math>\beta</math>. This implies that the [[least squares]] [[errors and residuals in statistics\|residual]]s <math>e_i</math> are "point-wise" consistent estimators of their population counterparts <math>E_i</math>. The general approach, then, will be to use <math>X</math> and <math>e</math> to devise an estimator of <math>Q</math>.<ref>Greene, William H. 1997. Econometric Analysis. 3rd edition</ref> What this means is that as the time between error terms increases, the correlation between the error terms decreases. The estimator thus can be used to improve the [[ordinary least squares]] (OLS) [[Regression analysis\|regression]] when the variables have [[heteroskedasticity]] or autocorrelation.
