Two small-sample tests for random coefficients in linear regression are derived from the Maximum Likelihood Ratio. The first test has previously been proposed for testing equality of fixed effects, but is here shown to be suitable also for random coefficients. The second ...

Regression coefficientsareestimatesof the unknownpopulationparametersand describe the relationship between a predictor variable and the response. In linearregression, coefficients are the values that multiply the predictor values. Suppose you have the following regression equation: y = 3X + 5. In this eq...
On the Bias of Some Least-Squares Estimators of Variance in a General Linear Model In particular, we give, for arbitrary design matrices of full rank, attainable bounds for the bias of the least-squares estimator of the variance of arbitrary linear functions of the estimated regression coefficien...
Noun1.regression coefficient- when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line ...
The article considers the predictive efficiency of some improved estimators of coefficients in linear regression models, constructed with the help of the Stein rule when there are some stochastic linear restrictions on the vector of unknown parameters. Assuming the distribution of disturbances to be not...
Regression analysis is a form ofinferential statistics. The p values in regression help determine whether the relationships that you observe in your sample also exist in the larger population. The linear regression p value for each independent variable tests the null hypothesis that the variable has...

In the case of linear regression, one additional benefit of using the log transformation is interpretability. Example of log transformation: right — before, left — after. Source As before, let’s say that the formula below presents the coefficients of the fitted model. Intercept (a) ...
Having estimated a linear regression with p coefficients, one may wish to test whether m additional observations belong to the same regression. This paper presents systematically the tests involved, relates the prediction interval (for m = 1) and the analysis of covariance (for m > p) within ...
