For the OLS estimators in a classical linear model to have average partial effects interpretation, one usually imposes the so-called “strict exogeneity”condition. In practice, testing strict exogeneity condition can be done by omnibus nonparametric test. However, there are cases where strict exogeneity condition fails but the average partial effects interpretation of OLS estimator still survive...

The performance of Construction Management (CM) students in their undergraduate studies is believed to be dependent on their mathematics and physics performance. The overall performance of students is measured by their overall Grade Point Average (GPA) for this study. Similarly, the performance of students in mathematics and physics are measured by the respective GPAs in these subjects. This st...

Consider a procedure that chooses fe-bit odd numbers independently and from the uniform distribution, subjects each number to t independent iterations of the strong probable prime test (Miller-Rabin test) with randomly chosen bases, and outputs the first number found that passes all t tests. Let pfc , denote the probability that this procedure returns a composite number. We obtain numerical upp...

The estimation of the age of a speaker from his or her voice has both forensic and commercial applications. Previous studies have shown that human listeners are able to estimate the age of a speaker to within 10 years on average, while recent machine age estimation systems seem to show superior performance with average errors as low as 6 years. However the machine studies have used highly non-u...
