This note discusses the effect of autocorrelated distrubances when they are not modelled on the statistics used in drawing inferences in the multiple linear regression model. It derives biases for the F and R 2
Using constrained multiple regression, the characterization of variate similarity basic to any assessment of SA can itself be framed according to the information present in the measure of spatial separation. These extensions obviate the inherent arbitrariness in how SA is usually evaluated, which now ...
The regression model includes the intercept term. It is not present as in the case of the regression through the origin, it is essential to return the regression including the intercept term to obtain the RSS. The explanatory variables, $X$ are non-stochastic or fixed in repeated sampling. T...
(1), where I is an n-by-n identity matrix, 1 is an n-by-1 vector of ones, T is the matrix transpose operation, and (I − 11T/n) is the projection matrix commonly found in conventional multivariate and regression analysis that centers the vector Y. The extreme eigenvalues of matrix...
researchers historically have interpreted the remit implied by this concern very narrowly, focusing their attention exclusively on autocorrelation in the residuals of an OLS regression analysis. Construed so narrowly, autocorrelation is—to use Hendry's characterization—a “nuisance,” with traditional “...
When performing multiple linear regression using the data in a sample of sizen, we havenerror terms, called residuals, defined byei= yi– ŷi. One of the assumptions of linear regression is that there is noautocorrelationbetween the residuals, i.e. for alli ≠ j,cov(ei,ej)=0. ...

Multiple regression quadratic assignment procedures (MRQAP) tests are permutation tests for multiple linear regression model coefficients for data organized in square matrices of relatedness amongnobjects. Such a data structure is typical in social network studies, where variables indicate some type of ...
