Question

The Durbin-Watson statistic (DW) is used to detect the degree of autocorrelation in regression analysis. When DW is closer to 0, it indicates that there is a ______ autocorrelation in successive residual ( or error) terms.
A. Negative B. Positive C. No or zero D. Inconclusive The Durbin-Watson statistic (DW) is used to detect the degree of autocorrelation in regression analysis. When DW is closer to 0, it indicates that there is a ______ autocorrelation in successive residual ( or error) terms.
A. Negative B. Positive C. No or zero D. Inconclusive
A. Negative B. Positive C. No or zero D. Inconclusive

Explanation / Answer

The correlation coefficient computed from the sample data measures the strength
and direction of a linear relationship between two variables. The symbol for the sample
correlation coefficient is r. The symbol for the population correlation coefficient is rho

The range of the correlation coefficient is from -1 to +1. If there is a strong positive
linear relationship between the variables, the value of r will be close to +1. If there is a
strong negative linear relationship between the variables, the value of r will be close to
-1. When there is no linear relationship between the variables or only a weak relationship,
the value of r will be close to 0.

[ANSWER]
C. No or zero
