Zhang, Chunming; Lu, Yuefeng – International Journal of Mathematical Education in Science and Technology, 2004
A family of integrals over infinite intervals appears frequently in the statistical literature on non-parametric regression. This note presents two simple transform methods, based on beta function and Parseval identity, to explicitly evaluate these integrals. These methods will benefit researchers and practitioners working in non-parametric…

MacKay, Andrea P.; Duran, Catherine – Centers for Disease Control and Prevention, 2008
This report presents data on the current status of adolescent health. Many of the measures of health status are shown by single year of age or by 2- or 3-year age intervals to highlight the changes that occur in health status as adolescents move through this important developmental period. Summary measures combining 5- or 10-year age groups (the…
