This paper investigates the effect of the nonzero autocorrelation coefficients on the sampling distributions of the Durbin-Watson test estimator in three time-series models that have different variance-covariance matrix assumption, separately. We show that the expected values and variances of...

type="main" xml:lang="en" <title type="main">ABSTRACT</title> <p>It is common sense that refill packs can increase the repeated use of durable goods, reduce resource waste and be conducive to environmental protection. However, their existence also has an economic effect. For instance, we find that the profit of a...</p>

This paper demonstrates the impact of particular factors – such as a non-normal error distribution, constraints of the residuals, sample size, the multi-collinear values of independent variables and the autocorrelation coefficient – on the distributions of errors and residuals. This explains...

This paper examines the distribution of the Lagrange multiplier test, LM test, and focuses on what factors affect the distribution of the LM test estimator. It is worth noting that due to Chi-square distribution properties, the degree of freedom depends not only on the lagged-number of...
