Parent Effectiveness Training (P.E.T.) is a parent education program based on the Gordon Model by Thomas Gordon. Gordon taught the first P.E.T. course in 1962 and the courses proved to be so popular with parents that he began training instructors throughout the United States to teach it in their communities. Over the next several years, the ...
Financial risk modeling is the use of formal mathematical and econometric techniques to measure, monitor and control the market risk, credit risk, and operational risk on a firm's balance sheet, on a bank's accounting ledger of tradeable financial assets, or of a fund manager's portfolio value; see Financial risk management.
The Gordon–Loeb model is an economic model that analyzes the optimal level of investment in information security. The benefits of investing in cybersecurity stem from reducing the costs associated with cyber breaches. The Gordon-Loeb model provides a framework for determining how much to invest in cybersecurity, using a cost-benefit approach.
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).

Another approach to model risk is the worst-case, or minmax approach, advocated in decision theory by Gilboa and Schmeidler. [22] In this approach one considers a range of models and minimizes the loss encountered in the worst-case scenario. This approach to model risk has been developed by Cont (2006). [23]
The NCAV strategy produced a return of 33.7% compared to 12.1% for the benchmark. [5] A 2014 study found that the NCAV strategy produced an annualized geometric return of 24.7% from 2003 to 2010; the excess returns were unexplainable by either the capital asset pricing model or the Fama-French-Carhart model.

Regret theory is a model in theoretical economics simultaneously developed in 1982 by Graham Loomes and Robert Sugden, [1] David E. Bell, [2] and Peter C. Fishburn. [3] Regret theory models choice under uncertainty taking into account the effect of anticipated regret. Subsequently, several other authors improved upon it. [4]
