Demographic and economic trends in medical schemes--a time series analysis [Demografiese en ekonomiese tendense vir mediese skemas--'n tydreeksanalise.]
Hartshorne J.E.; Carstens I.L. - 1991
A time series analysis was performed on medical scheme statistics with the aim of determining current and future demographic and economic trends. This would enable one to reach a better perspective on the current and future financial dilemma presently experienced by medical schemes. Data for the...

Estimation of expected value for lognormal and gamma distributions. [Environmental pollutants]
White, G.C. - 2009
Concentrations of environmental pollutants tend to follow positively skewed frequency distributions. Two such density functions are the gamma and lognormal. Minimum variance unbiased estimators of the expected value for both densities are available. The small sample statistical properties of...

Hanford transuranic analytical capability
McVey, C.B. - 2009
With the current DOE focus on ER/WM programs, an increase in the quantity of waste samples that requires detailed analysis is forecasted. One of the prime areas of growth is the demand for DOE environmental protocol analyses of TRU waste samples. Currently there is no laboratory capacity to...
