The hazard ratio is the effect on this hazard rate of a difference, such as group membership (for example, treatment or control, male or female), as estimated by regression models that treat the logarithm of the HR as a function of a baseline hazard () and a linear combination of explanatory variables:
However, no mathematical model is 100% accurate, so while the O-score may forecast bankruptcy or solvency, factors both inside and outside of the formula can impact its accuracy. Furthermore, later bankruptcy prediction models such as the hazard based model proposed by Campbell, Hilscher, and Szilagyi in 2011 [5] have proven more accurate still ...

In practice the odds ratio is commonly used for case-control studies, as the relative risk cannot be estimated. [1] In fact, the odds ratio has much more common use in statistics, since logistic regression, often associated with clinical trials, works with the log of the odds ratio, not relative risk. Because the (natural log of the) odds of a ...
The current ratio shows a company’s ability to meet its short-term obligations. The ratio is calculated by dividing current assets by current liabilities. An asset is considered current if it ...
A concept closely-related but different [2] to instantaneous failure rate () is the hazard rate (or hazard function), (). In the many-system case, this is defined as the proportional failure rate of the systems still functioning at time t {\displaystyle t} (as opposed to f ( t ) {\displaystyle f(t)} , which is the expressed as a proportion of ...
Ratios should generally be compared within an industry. A high ratio indicates the following: Company is maximizing its use of assets. This may mean a good utilization of assets and an effective ...
Other costs included in a fund’s expense ratio are taxes, legal fees, accounting, auditing and recordkeeping. While operating expenses can vary for mutual funds, the expense ratio tends to be ...
