Arbitrage pricing theory (APT) holds that the expected return of a financial asset can be modelled as a linear function of various macro-economic factors, where sensitivity to changes in each factor is represented by a factor specific beta coefficient. ... Rates of Return (ROR): can apply to a number of different equations, these are as follows: using the illustration that is to your right, these figures will help define the difference between each catagory. ... A random variable is a term used in mathematics and statistics. ... In mathematics, linear combinations are a concept central to linear algebra and related fields of mathematics. ... For other uses of the term white noise, see white noise (disambiguation). ...

Low testosterone in men may be diabetes risk factor
After the influence of age, race and obesity was factored in, men with the lowest levels of testosterone were four times more likely to have diabetes than men with the highest levels.

Risk factors are genetic factors, certain rare inherited syndromes such as neurofibromatosis, being a parent or sibling of a child with brain cancer, high doses of ionizing radiation, and occupational exposure to certain aromatic hydrocarbon compounds, bis-chloromethyl ether, vinyl chloride, and acrylonitrile.
