In regression analysis, the unbiased estimate of the variance is

A) coefficient of correlation.
B) coefficient of determination.
C) mean square error.
D) slope of the regression equation.

Unbiased Estimate

A statistical estimate that is equally likely to be above or below the true population parameter, showing no systematic error.

Variance

A measure of variability that describes the average of the squared differences from the mean for a set of data.

Coefficient Of Determination

A measure, often denoted as R^2, that indicates the proportion of the variance in the dependent variable predictable from the independent variable(s).
